>> this is cnn. >> the world's news network. >> this is cnn breaking news. >> thanks for joining us. i'm isabel rosales. >> we begin with a second aviation disaster in a major u.s. city in less than 48 hours. several hours ago, a medevac jet with six people on board crashed in philadelphia. it was caught on video. take a look.

>> allahu akbar. allahu akbar. what the hell? what the hell? what the hell? oh my god! oh my god! la. there's a plane, bro. that's a plane! i caught that on camera. yo, yo you can hear the panic and the fear there in the city of brotherly love. >> officials say the plane plunged shortly after takeoff from a nearby airport before exploding into this massive fireball. there's no official word on casualties, but the plane's operator says it cannot confirm any survivors. philadelphia's mayor says several houses and cars. they were impacted by the crash, but no reports so far on any fatalities there on the ground. the plane's passengers sadly included a child patient and her mother. firefighters say the blaze at the crash site is now under control. the incident

followed wednesday's mid-air collision between a passenger plane and a helicopter near washington, which left 67 people presumed dead. new audio reveals the air traffic control tower losing contact with that medevac jet. listen. >> medevac med service 056. contact. philly departure 123.8. >> 1 to 3.8. gadi eisenkot sierra. 056 medevac. thank you. good day. >> medevac med service 056. >> northeast tower. contact philly 123.8. medevac med service northeast tower. medevac med service 056. northeast tower. are you on frequency? >> approach to runway two four. what's going on. >> down there? >> keshet 765. we have a lost aircraft. we're not exactly sure what happened, so we're trying to figure it out for now. >> an earlier cnn's anderson

cooper spoke with mary schiavo, a former inspector general at the u.s. transportation department, and she sent video similar to the ones we've been seeing. they speak volumes about the incident. >> this is a. >> very complicated situation right now. >> right. and i think the biggest clue came in that video footage that we've seen where the plane came literally straight down out of the sky. there would be no way to control that plane descending totally out of loss of control. and it had a slight spin on it. and that would indicate. >> this is the video that you're talking about. >> yes, that is a plane. >> totally. it's going straight. straight down, straight down. >> they could not have maintained any control. they would have had no ability to direct it away from people, from traffic, or even attempted emergency landing on a on a road. there's just no way that is a plane completely out of control. >> i just want to play that ring camera again with just the sound. when us not talking over it so our viewers can hear those who are just joining right.

have you have you seen that before? >> like like that? you mean on other planes? no, i mean, that is an unbelievably just straight down descent, which means whatever happened, happened obviously up at altitude and left it unable to be controlled. now, just for that vision right there, it looks almost like there's some sort of an explosion or fire, but it could be a reflection. i have to say, you can't tell. >> for sure on the ring camera. that's right. the way the light is. >> very difficult to tell. i mean, it's great that the ring camera captured as it was, but for a second it looks as though something was was doing that. but this this is clearly not you know what what often you see, it's not spatial disorientation. it's not loss of situational reference. it's clearly not fuel starvation. something went terribly wrong on that plane to make it fall like that. >> something went terribly wrong on that plane to make it fall like that. well, we did speak

with the plane's operator, which told cnn the aircraft was in flying in excellent condition with experienced crew there in the cockpit. they were actually taking the patient back home. a child patient to mexico after the girl's medical treatment. jason carroll has more from the scene. >> we can see the area here is still cordoned off. there are emergency vehicles right down here. this is cottman avenue and roosevelt boulevard. the impact of the crash, several blocks in that direction. this is a community in northeast philadelphia that is simply in shock. when you look around and you see where this happened. this is a business district. the roosevelt mall here is in the area. a number of businesses, a number of residents as well. a number of row houses. this is an accident that happened just about after 6:00. this is rush hour. and so you had any number of people in the area who were out and about who saw what

happened. eyewitnesses say they saw a fireball upon impact. some people saying that the sky simply lit up. not only did people see it, but they felt it as well. some eyewitnesses saying that their windows were rattling. they went outside to see what was going on and saw the fires that had erupted on the ground. philadelphia's mayor says at this point, she could not confirm how many fatalities they are. there are. we can tell you that some eyewitnesses say that they did see some victims who were here on the ground. we can tell you that on board that learjet 55 that meta medevac jet aircraft were six people on board, four crew members, two passengers, a young girl and her mother. the young girl was here in philadelphia receiving medical treatment. she had been cleared to fly. the aircraft was in route to missouri, where it was going to refuel and then head on

to mexico. all on board, we are told, are mexican nationals. now, when this aircraft crashed here in northeast philadelphia, the mayor says that a number of buildings, a number of vehicles were impacted. more than 100 philadelphia firefighters responded to the scene doing what they could to get those fires out just as quickly as they can. at this hour, a number of agencies here at the scene, including the ntsb, the faa doing the early stages of their investigation. already we're hearing from officials that because the crash scene is such a wide area, they're telling people who live here in the area if they see any debris, any parts of the plane, not to touch it, to immediately call 911 so folks can get out there and do the process of beginning to retrieve pieces of the wreckage. at this point, once again, the early stages of this investigation to try and sort out exactly what went wrong

here. jason carroll, cnn, philadelphia. >> and for more on this, we're joined by david soucie, a cnn safety analyst and a former faa safety inspector. he's speaking with us from denver. david, thank you so much for joining us today. we really appreciate your perspective in all this. let's first talk about the videos right. that ring camera that captured that plane falling down. the dash cam footage we saw from a car as well. um, it's just it's striking the speed that this plane just goes down right into the ground. the data shows the speed of descent was 11,000ft per minute. what can cause a jet to fall out of the sky like that? >> well, there's only a few things that can cause that. it's too early to know exactly what happened yet. but as mary pointed out before, it's not about engine starvation. it's not about some ordinary thing that happens that's recoverable. this was not recoverable. that airplane is

completely out of control. one of the things that i speculate about is the fact that in a stall condition. now, on that lear 55, i was involved in the in the stall characteristics check of that aircraft back in the late, uh, back in the 70s. and what we did back then was we stalled the aircraft intentionally at an altitude of 50,000ft. we went to the max altitude and tried to stall the aircraft, and we did. and it usually buffetts. but when you set the the weight and balance, when the balance of the aircraft is off at that point and you do a stall, it can be. uh non-recoverable. the aircraft nose will drop dramatically if the weight and balance is off. and then once it does, it is down. it's going straight down. then the experiments that we did with moving the ballast to the rear of the aircraft, the stall was almost unrecoverable. it took us almost 20,000ft to recover from the stall. so in that case, this lear 55 is is.

and most lear jets are built for speed. they're made to be fast transport aircraft. and so when things go wrong, they go dramatically wrong very quickly. and that's the only thing i can think of that would cause this type of, uh, dramatic drop in that short amount of time. >> yeah. so if i'm understanding you. right, you're saying that this learjet 55 it's vulnerable to stalling out. it's it's finicky. it has some nuances involved with how you fly it to avoid stalling out. can you talk more about those nuances? and do does any of the equipment that would be on a medevac flight? gurneys, for example, when thinking about weight, would any of that play a role? >> well, it can. and what i'm referring to with, with the vulnerabilities are things that are trained when you're trained to fly that aircraft. flight safety international teaches pilots how to do this and how to manage their fuel inside of the lear jets. lear jets have swept wings so as the fuel is burned off, it does change the weight and balance somewhat. in this

case, i'm sure that that aircraft was full of fuel. it was heading down to a 1100 or 1200 mile flight, and that aircraft can go 2300 miles, so it's at least half full of fuel, but it has a tank in the rear of the aircraft. it also has tanks in the wings. so the way that you manage that fuel, it can change the weight and balance. if you put too much fuel in the back, back, uh, tank. so that can change that. but pilots are trained to do that. so i can't say that that's what caused this. i'm just saying that that's one of the things that pilots are aware of and how they manage their fuel in the aircraft. now, your second question about the medevac kit that's inside. i worked for a medical transport company for many years, helped design the medical transports, and then later was an accident investigation up in casper, wyoming, of a medical mitsubishi mu two that crashed, and when it did, it had a medical kit inside of it. now, what can happen? there is the medical box that's in there, contains oxygen and

sometimes very large oxygen bottles go along with that. so when we look at the explosion at the end, it's atypical. it's an extremely violent explosion. >> you're saying the oxygen could have played a role in that explosion? >> most definitely it could have. yes. that's what i'm saying, as it did with the accident investigation i did in casper. the same thing happened there. >> okay. and this medevac plane is scheduled for 2 to 3 flights per day. so this is this is a workhorse of a plane to something like a maintenance schedule come to mind for you, or is that not a factor based on the videos that you've seen? >> no. these aircraft are made to to be used that way. and the fact that the pilot does a preflight on every flight, no matter if it's 3 or 5 flights that day, the pilot does walk around and the maintenance schedule is very tight and, uh, jet rescue is a very good operator and has a very good safety record. so i don't think i don't suspect any maintenance issues. >> hey, this was very important context. david soucie. we really

appreciate your perspective in all this as we cover this tragic news. thank you. >> thank you. isabel. >> all right. we're taking a quick break. when we come back, we'll have the latest on the breaking news that we're covering the crash of an air ambulance jet into a philadelphia neighborhood. stay with us. >> superman. >> the christopher reeve story sunday. >> at eight. >> on cnn. >> at morgan. stanley. >> old school. >> hard work meets. >> bold new thinking. partnering to unlock new. >> ideas to create. >> new legacies, to transform a company. industry economy generation. because grit and vision working in lockstep puts you on the path to your full potential. old school grit, new world ideas, morgan stanley.

twin engine learjet 55 hit the ground. so far, the air ambulance company that organized the flight will only say it cannot confirm survivors. also, no word on fatalities there on the ground, though. cnn affiliate kuow reported several injuries. one local hospital told cnn that it treated six patients after that crash, and three have already been discharged. officials say multiple buildings and cars were affected. listen to one witness and how they describe what he saw. >> i was in shock. i'm still in shock. like this is insane. why can this. and before that, to be honest, in my mind, i thought like, what if the rocket would like. cause i'm from ukraine, right? and there is war. there's always rockets coming in and stuff like that. and then i see, like, things flying, like, no way. the war started again, you know. and you say you

never know just horrible. >> horrible. well, joining us now from philadelphia is ryan tian, who witnessed the crash. ryan, i'm so sorry to be meeting you under these circumstances, but i do appreciate you joining the show. can you take us from the start what it is that you saw? >> yeah. >> so initially what i saw was a massive, like, flash in the sky. that kind of lit the entire sky as far as i could see. like bright orange. and then i turned around because there was a massive, like. like shock wave. and then i turned around and saw, like, a massive mushroom cloud just over the horizon of like, homes. >> what did you think in that moment when you saw that? >> i it was just like complete shock. i thought we were being

attacked by somebody, you know. >> like a terrorist attack. that's the first thought that came to your head just because of how massive that fireball was something like that. >> like it felt like a missile. you know? like yeah. >> can you tell me, ryan, what you did next when you saw that? >> i mean, i, i just whipped out my phone, took a few pictures, and then i called everyone i knew in the city. >> yeah. can you tell me about that area? this happened shortly after 6 p.m. so rush hour in the vicinity of roosevelt mall on cottman avenue. for folks who don't live in philly. what is that area like? >> it's very congested at this time of day. like it's pretty. you can almost expect your, uh, commute times to double. people

everywhere, especially like where the crash took place right. >> so exactly the worst type of spot for something like this to happen. unlike, um, obviously still very tragic what happened in washington. but that was in the potomac. this is a very, um, well versed area, well traveled area during rush hour. how are you doing, ryan? after witnessing this? >> i was definitely a little shaken up, but i think i've settled down. >> do you live near the area? do you feel safe sleeping there at night? >> um, i don't live in the area. i'm here visiting my girlfriend. but, um. yeah, it was definitely pretty traumatic for something to. what? for a plane to fall out of the sky, like, less than a few miles away

from here. >> so you took some videos. you were calling up people because obviously and understandably, this is very shocking what's happening in front of you. did you get closer at all to where this happened? did you see anything there on the ground? we've heard from other witnesses that they saw people that were injured, or worse, people that were killed from this. is there anything that you saw there on the ground? >> no, i, i saw the fireball and i just got the hell out of there. >> yeah. have you been on social media? have you seen some of the videos, like the the ring camera that caught the descent of this plane? >> yeah, definitely. it just went straight down. almost 90 degree. >> what did you think in that moment? and seeing that and what questions do you have? >> i just don't know how something like that would be possible. like to just like, basically drop out of the sky in

midair, like, no, like control, like, you know, crazy descent or anything. so really, just like. i'd like to know how you know. >> how something like that could happen. of course, we know the ntsb is on the ground or will be there shortly to conduct an investigation and find the why to this question. and that could take some time. ryan. um, aviation safety has been taking over headlines. we've seen so many close calls that have been reported. obviously, these are two back to back aviation disasters in just 48 hours between washington and philadelphia. we saw over in south korea that crash that happened over there. we know statistically that aviation travel is probably the safest there is out there. but just as a human witnessing these images, especially these back to back incidents, um, do you feel comfortable flying or does it raise any questions for you?

>> yeah. like i especially after back to back incidents in d.c., first d.c. and now this definitely like, you know, wouldn't feel very comfortable flying hopefully until they, you know, figure it out. we don't we don't know how long that's going to take. but. >> yeah ryan thank you so much. i appreciate your time and you sharing with us what it is that you saw, what you experienced as philadelphia is really hurting and washington as well, from these tragic events. ryan, thank you. >> thank you. have a good night. >> thanks. well, the area around the crash site, as we mentioned, is busy and densely populated. a shopping mall is nearby there, and streets are lined with row houses. the explosion set homes and cars on fire. this is how first response firefighters alerted that situation. >> my location two story. ended

around 16 by 45. the. we've got heavy fire in the dwelling. we got fire spread out across the street. multiple vehicles. i'll give you a further report on that at all companies. proceed and go to service. >> at kelly. president of the international association of firefighters, spoke to cnn earlier about the massive response from emergency crews and the challenges that they face. here's what he told my colleague kaitlan collins. >> the philadelphia. >> firefighters actually struck. >> three alarms for this, which brings about 150 firefighters. they also declared it a mass casualty incident, which brings about ten ambulances in the paramedics that, uh, that we also represent in philadelphia. um, when you have these jet crashes, any fire doubles in size in every minute. when you add an accelerant, it obviously

accelerates the fire with jet fuel. it's a particularly hazardous flame flammability to it. so we had multiple row houses burning in philadelphia. i've been talking to the firefighters on the ground there. they did affect rescues when they got there. um, so some of the people that were trapped in those buildings were saved tonight by the philadelphia firefighters. we had one philadelphia firefighter that was injured, and it's an unfolding scene. anytime you have those jet fuel incidences, you also need, uh, special types of firefighting foams to actually try to contain it as well. >> yeah. and what does that. >> how readily available. >> does a. >> city fire department have that? because obviously, you know, this was a plane that was taking a trip that was 1100 miles based on what we were told from philly to branson, missouri. and obviously there's a lot of fuel on that plane. is this something that every fire department has typically, what does that look like? >> well, all airport fire departments, which philadelphia is in charge of the philadelphia fire department protects the

airport. that particular air field where that plane took off from. i'm not sure if they're affiliated with the philadelphia airport. um, but those are airport crash. rescue crews always have large capacity foam on hand for jet fuel fires in the field. in city fire departments, some engine companies are designated as foam companies that bring that capacity with them to certain incidents. uh, the philadelphia fire department in particular. i'm not 100% sure exactly how they structure their foam response, but, um, i know that tonight they they they did a tremendous job trying to contain that fire from burning the whole block down. >> what does that look like when they get on the scene immediately in terms of if a house is on fire, but there's jet fuel everywhere. what what do they do first in that situation? >> well, oftentimes when, you know, when these jets crash into crowded neighborhoods, which happens from time to time, the first two apparatus don't always understand that it was a plane crash. a lot of times it just it

looks like a massive explosion. usually have fire rapidly spreading to multiple buildings, cars usually burning, which was the case here in philadelphia tonight. you saw that in some of the video. um, so the first objective is to save lives. so the first companies in are going to be looking at those buildings and seeing what is searchable in the buildings where they have, uh, fire that has not extended into that second floor that you just showed. they're going to go in and try to search that. they're going to get lines in place, hose lines in place to try to cut off that fire. um, it requires a lot of personnel. as soon as you can get them to try to contain that fire. and philadelphia is a very aggressive fire department. and, uh, tonight, you know, they were they were able to get, as i said, three alarms, about 150 firefighters on scene in rapid response and were able to contain that fire before it burned the whole block. >> ahead on cnn newsroom. a former medevac pilot joins us as we work to learn more about the air ambulance crash there in

and cars. they were impacted, but so far there are no reports on the number of fatalities. the crash caused a huge fire, which is now under control. cnn has obtained video taken on the ground by a bystander at the moment of the crash. watch allahu akbar. >> allahu akbar. what the hell? what the hell? what the hell? oh my god! oh my god! la la la la. there's a plane, bro. that's a plane. i caught that on camera. yo! >> stunning. stunning images there. a spokesperson for the company that operated the medevac flight tells cnn that the jet was well maintained and in good shape, with an experienced crew on board. take a listen. >> it's highly unusual for a plane to take off, right? to take off and crash right away. we simply don't know. we will have to wait patiently for this

accident scene to be cleared for the ntsb to step in. we will cooperate fully with the authorities. anything they need, we'll make available. this aircraft had an excellent maintenance record. it's a very reliable airplane that's been used before. >> and cnn's tom foreman has more on the company that was operating that flight. >> jet rescue is an air ambulance company, meaning they operate. very specialized planes, which they bill as intensive care units in the sky, meaning they have an awful lot of the equipment that you would normally need in a somewhat limited intensive care unit with medical experts on board, and they transport people in all sorts of very serious medical conditions all over the place. they're both licensed and insured in the u.s. and mexico, with some operating bases in both places. they have more than 20 years of experience, and they call themselves the premier provider of international

critical care ambulance services from mexico, latin america and the caribbean to the usa, canada and worldwide. although they seem sort of focused in that area, they also cite some specialty in handling pediatric patients, as we're talking about. in this case, they had nine lear jets in their fleet prior to this accident. according to their website. and they they boast on the website or mentioned on the website that they had a lot of training of their pilots, a lot of time in simulators, a lot of keeping their skills up. so there's also no real record, as far as i can tell of them. having had a serious incident anywhere in the past. so this is a company that has been relied upon by many, many, many people for critical medical transit. and now this incident has come into their record. >> brian, steve cowell, he's a former medevac pilot and an aviation safety consultant. he joins me this hour from denver, colorado. steve, thank you for joining us. you actually flew on

lear jets. not just that, but on the same model as this one that just crashed when you were looking at those videos of the plane just coming down that tremendous speed. what stood out to you? >> well, first of all. >> a medevac airplane is really. specifically designed. >> on the interior for patients. so one thing that i thought about was, was there a shift in load weight? and given the fact that everybody is strapped in in certain positions, it would just be inconceivable to me that there would be a shift in load weights. when the airplane was coming down at such a steep angle. it could indicate some sort of loss of control. now that learjet specifically has, it's called the stick pusher system, so that if the nose is raised too high and the lift is lost by the wing, the airplane

systemically will go ahead and push the nose over to regain wind flow over the wing to generate lift. i don't know, certainly no one knows at this point what happened. that's up to the ntsb to work through the investigation. >> yeah, but clearly with it falling down in the way that it was, um, this is catastrophic, totally out of control. you think something like weight could be behind it? can you hear me? steve? >> yeah, i could. >> yeah. >> i didn't catch the last part. >> sure, sure, sure. it was a catastrophic failure of some sort. right. you think something like weight could be involved in that? >> you know, we just don't know. and unfortunately, in this particular model and in actually all business jets, although they may have a flight data recorder, they're not going to have the

capability that we would have on, say, an airliner. so it's really a tough task for the ntsb to discern what had happened. but they'll be working on this for quite some time to try to find the answers to this mystery of why this plane suddenly plummeted to the ground. >> earlier this hour, we spoke with a former faa accident inspector who said that the learjet 55 is vulnerable and his experience is stalling out. he spoke to me about the nuances of the aircraft, which is very safe, he says. but there are particularities there with the care needed with weight that you just touched on and even which fuel tanks you fuel first. do you agree with his assessment that they are vulnerable to stalling out? >> no, i do not. i flew that airplane for two years and although it's a different sort of airplane, it has the tail of the airplane is called the t tailed airplane. just because of

the shape. so if the airplane were to suddenly pitch up, in other words, it could get into what is called a deep stall situation, which is really difficult to recover from. but those pilots were very experienced. they knew that airplane very well. i knew the airplane very well, and i can tell you that it was a wonderful airplane to fly, so i would not consider it particularly sensitive. you did have to fuel the plane in a certain way, you know, but that was to maximize the fuel loading. but other than that, no, i don't think it was really any more dangerous than any other plane. >> so you disagree? it is not any more vulnerable to stalling out than other aircraft. and you flew. you flew this this plane, the national transportation safety board, the ntsb, they are responding to this incident. what are their immediate next steps as they investigate now,

their second aviation disaster in about 48 hours. >> well, it's going to be a tough task. there are local ntsb offices, and those people are just as qualified as the go team was on the washington, d.c. accident. so what they're going to be doing is, first of all, gathering all the debris that they can. they're going to be securing all the aircraft records, all the air traffic control tapes, any data recorder from the airplane is going to be recovered. they're going to do whatever they can to assemble the pieces of this puzzle, and it's going to take them time to put it together. we're going to get a report, a factual report in about 30 days or so with regards to this accident, but it will not speak to the causation of the accident that will happen in about a year. >> a year. yeah. it takes a long time there, steve. can we talk about the timing of this, the

back to back, you know, aviation disasters? do you have any concerns that this is going to shake the confidence that people feel when it comes to flying as a mode of transportation? we know looking at the stats, this is the safest way to travel. but still these images, they're striking. >> they're very striking. and, you know, any aviation accident is going to be much more dramatic than maybe a car getting into an accident on the highway. but with every single accident, we try to learn and improve the system of safety. well, you know, it's just going to take some time. this was a unique situation. it was fundamentally a business jet used in medevac flights. everything that we have heard from the company, from everybody involved with this jet, everything was well maintained. pilots well trained and experienced. so, you know, it's going to be up to the ntsb. but

as far as the public should be, the public should not feel concerned about the system being unsafe. um, you know, every single day there's roughly 45,000 flights at any given time, there's 6000 flights in the air. we've got millions and millions of flight hours without any incidents or accidents. so, you know, unfortunately, now we have a microscope every time there's an aviation incident or accident. but. >> under a big mike feel, under a big spotlight right now, especially with so many close calls to that, we've been talking about at length for years now. steve cowell, very important perspective. thank you so much. we appreciate your time. well, stay with cnn as we learn more about the breaking news in philadelphia, an air ambulance crash with six people on board. stick around.

one local hospital told cnn that it treated six patients after the crash, and three of them have already been discharged. officials say multiple buildings and cars were affected. a philadelphia city council member provided more details about the busy area where that plane went down. listen. >> it appears. >> the plane went down into. >> a parking. >> lot area. >> where there were. >> cars and. stores just. >> across the street. >> as you mentioned. >> there's a. >> giant mall with many, many. >> many stores and. and then. >> right beyond the. stores on. both sides. we have residential neighborhoods. and i think what the video. >> you. >> just showed. >> was a. >> house very close that was getting a delivery. and all of a sudden the explosion hit. so what we're going with our first responders now is door to door to see if anybody knows homes were actually, you know, injured or or worse. there's first

responders vehicles moving in and out, whether they're taking them to the hospital or just responding to the homes or to the businesses or to the folks that were actually in the cars when that plane hit that sort of parking lot area. we we suspect the a lot will be going on as the evening progresses. >> cnn aviation correspondent pete muntean has more. now about the plane and the location where this crash occurred. >> we know, at least from the faa right now, confirming for us through an official source that this was a lear 55 business jet. to clarify, that is not the small single engine airplane that was initially reported as having gone down in this philadelphia neighborhood. this is a twin engine business jet of about ten tons of maximum weight, goes about 450mph. and the nt or the faa is also confirming to us that this flight just left philadelphia.

northeast international airport was on its way to springfield-branson national airport in missouri. that's a flight of about 1100 miles. so this plane would be fully loaded with fuel very likely, and would explain the large fireball that we have seen in these videos that keeps surfacing on social media. the early data, the preliminary data from open source flight tracking site ads-b exchange, also corroborated by flightradar24 that took off on philadelphia northeast airport's runway two four. that's to the southwest and was airborne for about 40s and was descending at the very end at 11,000ft per minute. that is an alarmingly high rate of descent. business jets like this in a normal descent descend at about 2500 or 3000ft a minute, depending on their speed. so there was a lot of detail emerging here. but of course, to underscore, things are very preliminary, very early to speculate on the cause of this crash. the most alarming thing

to me right now is the video surfacing from ring doorbell cameras that shows this plane essentially making a lawn dart like descent into this philadelphia neighborhood. it is not too far away from this airport, and it is very densely populated. of course, this will trigger a conversation about whether or not airports like this should be close to densely populated areas. remember, this is an airplane that is not particularly small. it's more akin in size to the regional jet that we saw involved in the mid-air collision, only a few thousand feet away from where i'm standing here at reagan national airport. >> and in washington, investigators have begun interviewing air traffic control personnel about that deadly mid-air collision. authorities have also recovered the so-called black boxes from the black box from the military black hawk helicopter that collided with that passenger plane on wednesday night. cnn's danny freeman has the latest from the nation's capital surveillance video obtained. >> by cnn showing. >> the final.

>> moments before the two aircraft collide. >> the type of evidence. >> investigators are sure. to examine carefully. >> as they work to determine what happened. >> we take. everything serious, every potential scenario, so it's helpful as we see all these different new pieces of evidence, whether it be eyewitness or video. in this case, those things help give us a lot more details. >> in the video. you can see the black hawk helicopter flying seemingly. >> as normal. >> straight into the descending passenger jet. neither aircraft appeared to try to avoid. >> the other. >> a sign they may not have seen. >> each other until. >> it. >> was too late. >> this, despite. >> the helicopter. >> pilots confirming to air. >> traffic controllers it saw the plane seconds before the crash. >> right now, it's too early to speculate on what exactly occurred, but you've got a lot of different moving parts, so we're in the early stages. >> now, the. >> altitude of the black hawk helicopter. >> is coming under increased scrutiny. >> flight tracking data from the company flightradar24. >> appeared to. >> show the helicopter was flying 100ft above the maximum

allowed altitude and veering off the prescribed route along the east side of the potomac river. on friday, cnn learned the federal aviation administration indefinitely shut down the low altitude helicopter corridor used by the black hawk. on wednesday night, lawmakers are looking to see if permanent changes are needed around one of the busiest runways in the country. >> what the video shows is that they were flying. >> at the same. altitude at a moment when that shouldn't have happened. that somewhere. in the process of what is now. established as. >> these two routes, which i think will raise a lot of. >> questions for. >> lawmakers to discuss, how is how are those two routes and even the level of separation that is expected? how could how how are we even doing that? >> investigators now have their hands on the airliners, two black boxes, the devices crucial to understanding what may have happened in the final moments of that flight. meanwhile, recovery efforts continued on the cold and rainy potomac river friday. d.c. officials determined to recover every victim under the

water. whatever it takes. >> yes, we. expect to recover. >> all of the bodies. >> that's why. >> our teams are still working. we're going to have to work with the salvage company to do some of that work. >> we've got more breaking news out of the middle east. we're looking right here at live pictures from khan younis gaza, where two of the three hostages set to be released today, have been handed over by hamas, ofer kalderon and yarden bibas were just handed over to representatives of the red cross. expected still to be released is keith siegel, an israeli american. we have pictures here now. take a look right there in the middle that is seagull. seagull's family had this reaction when they learned he was being freed. >> we don't know. i'm a i'm a. >> segal's wife was also abducted, but she was released in november of 2023. in exchange for the three men. israel is scheduled to release 183
