let's go to our aviation specialist with nbc news, tom costello. tom, with a long good morning to you, i know you've been up following this for quite some time. before the break -- i'm sorry, tom, we've just lost, we'll get him back in just a moment. let's go to greg feith, a former ntsb investigator. i know that tom was making the point. similarities to this crash with that, again, if it is a crash, with that of the egyptair flight over the sinai peninsula which crashed killing many, many onboard. over 200, and that was on october 31st of this last year. talk about the similarities there and if you think there are some parallels. >> when you look at it, alex, both airplanes were in the cruise phase of flight. that is the lowest workload for flight crew members. it's basically monitoring systems. the airplane is being operated on autopilot. so there isn't really a lot going on with the airplane from a dynamic standpoint if you will. they were both in radar coverage. there had been normal communications. and then of course both airplanes suddenly dis

joining me right now is tom costello, our aviation expert. where is this leading you after talking ago this for the last six hours or so, when you look at where this plane disappeared, 37,000 foot altitude, no peep from any crew on board. i know it's somewhat speculative at this time, but there are a couple of educated guesses you could take. >> well, listen, the lack of a distress call or mayday call is concerning here. that would suggest that the pilots didn't even have time to get on the radio and say mayday or say oh crap or whatever they might say. that would suggest this was very fast indeed. that whatever happened it was immediate and it was cataclysmic. they had no chance to respond. so that really leaves with two really leading theories. not the only theories, but theory number one, there was some sort a breakup in flight. a catastrophic breakup involving the fuselage and the plane literally came apart in air. number two, this plane may have been brought down by a bomb. the reason i'm less inclined to go with the theory it was a cata

tom costello? >> we are getting word from the egyptian authorities they believe the plane has crashed. widely reported now on the associated press that this plane, again, to repeat this is egypt air 804, 66 passengers and crew members on board en route from paris to cairo, egyptian authorities say has crashed, we believe, some where over and into the mediterranean sea. airbus a-320 built in 2003, you may recall, on board, a total of 66 people. the pie loot, 6700 hours in light. and the co-pilot, 2700 hours. a respectable amount of time in the cockpit. whether there was anything unusual in the cargo hold. initial reports from the airline suggest it is very, very early hours in the investigation and knowing exactly what was in the cargo hold and who was in the plane will take some time and a good deal of forensics and also good old, hard detective work. clearly done by the egyptian authorities and the french authorities. as to who is in charge, it's a e egyptian aircraft. they would have the priority

let's go now back to tom costello who is covering this story. r you. his bottom line is nothing more than the plane has disappeared and that they've released nine press releases. >> yeah, i think you're right. and he went on to say there were several attempts to contact the plane. that's confirming other reports we heard out there as well. and then, of course, if you match that up with what the greek military is saying that they detected, their military radar detected what appears to be the plane falling from the sky, and it would appear spinning or doing one or two 360s as it fell to the mediterranean sea. all of that falls into this narrative of how this may have happened. and it would suggest that whatever happened was catastrophic and it was quick. in other words, it does not appear this pilot ever had any time to consider any sort of emergency landing. there was no radio call. there was no attempt at a controlled descent. no dramatic slowdown. it was just all of a sudden, the plane is falling from the sky. so whatever precipitated that, of c

nbc's tom costello says there are indications of whatever happened, happened quickly. if this plane broke up in flight or there was an explosion, whatever happened, there simply wasn't enough time for the crew to even say may radio. >> watch for updates throughout the newscast and on the nbc washington app throughout the day. >> now to breaking news out of mexico. the new work schedule for the metro program is out. >> this whole plan that metro has been warning people about starts june 4th. let's take a look at exactly what is happening here. the first major project is on the orange and silver lines from june 4th to june 16th. it will be 13 straight days between the boston and east falls church station. that's going to have major impact to 73,000 weekday trips. most orange and silver lines here will only run around every 18 minutes. that's around the clock. and a complete shutdown on the blue, orange and between eastern market and benning road and that will be from june 18th till july 3rd, 61,000 weekday trips impacted there. in total there are 15 of these major projec

. >> tom costello who covers aviation says at this hour the leading theory for the aircraft disappearance is terrorism. we are learning flight ms-804 had its last communication with greek officials. no signs of distress at that time ten miles from egyptian air space. it had 66 people on board. per hour and at ap n altitude o 37,000 feet, tom reported that survivors would be highly unlikely. and the fact it just vanished implies something instant and catastrophic. we're expecting an update on this story in a little more than an hour. watch for high updates on twitter and facebook. >>>. >> again they're still work to go find out why this plane is missing and nothing is confirmed. egypt err says the pilot was very experienced, more than 6,000 hours of flying time.air y experienced, more than 6,000 hours of flying time. airbus says the plane itself has spent some 48,000 hours in the air since it was built in 2003. >>> right now montgomery county police are investigating a threatening tweet sent to a student at paint branch high school. molette green is live with more on how the principal is r

that was a question that tom costello had as well. and that there about no issues in leaving that airport in paris. everything went smoothly from that airport in paris on the departure side of things. obviously potentially catastrophic news on the arrival side of things. we should remind our viewers it's now been about three hours and 30 minutes since this plane first went missing. >> and that's really important because -- and the fact that it is starting to get daylight outside, hopefully we can get some more information into our newsroom as to exactly what happened, what they're seeing, where these search and rescue operations are, and what they've been able to gather at this point. captain ross aimer is a former pilot and a security expert. he joins me now on the phone. we've been talking with tom costello and cal perry about the different radar that is monitoring that area and how maybe a military radar could pick up something that the commercial airline radar wasn't able to see. is there still hope in that at this hour? >> good m

tom costello, nbc news, washington. >>> we're back in a moment with how this smash hit musical about history has just made history of its own. >>> there is a new development tonight about one of the most famous images in u.s. history, the flag raising on iwo jima during world war ii. the marines are looking at new evidence of who actually raised that flag. and the famous son of one of them says for the first time he's convinced the marines got it wrong. nbc's pete williams with the stunning new twist. >> reporter: as u.s. marines stormed the island of iwo jima off japan, six american servicemen raised the u.s. flag. and the photo of that moment became one of the most famous in history. for seven decades, the marines have identified five of their own in that picture along with a navy corpsman, john bradley. that photo inspired the marine war memorial in washington. now historians say john bradley was not among the six men cast in bronze. his son james wrote the bestselling book "flags of our fathers," made into a hit movie directed by clint eastwood. now for the first time he tells nb

back to you. >> tom costello, thank you so much for walking us through all of that. ayman, i want to bring you back in. tom just raised an interesting point. investigators looking at where this plane had been before it took off from here in paris to cairo. tunisia. eritrea. what do we know about those places with regards to airport security? what do we know about that part of the world? >> we know that tunisia has a much smaller airport, and security there, there are no direct flights from tunisia to the united states. there are flights from tunisia to europe. there is some standard, international standard that tunisia must abide by. but is there a vulnerability in all of these smaller airports in some of these countries? many that rely on conscripts for security at some of these access points around the airports. t the answer to that is yes. and tunisia has experienced some terrorist attacks. they have a robust presence of militant groups in libya that have made it their point to try and carry out attacks and infiltrate attacks in tunisia. we're getting way ahead of

i want to go back to tom costello. with his conflicting reports, as to whether egyptian officials do have some distressed report. a pinging or something like that, it looks like they're backtracking on that. that isn't unusual. a couple hours after the disappearance of a plane, it is not necessarily logical to immediately find some pinging sounds coming from under the ocean, for example. >> we're dealing with a part of the world with conflicting information. it is difficult to get a straight answer. that said, let's make the following point. this body of water. the mediterranean sea is of course crawling with navies from not only europe and the united states, and russia but of course, the egyptians have their navy, the israelis have their navy, the greeks have their navy, the turks. there is a tremendous am of activity because of the geopolitical and the strategic interests involved. also the immigrant situation there with the syrians and libyans. fleeing their countries and trying to make it to europe. there is no sho

have, as you probably know by now, three people dead over the course of the last 24 hours. >> tom costello, stand by for us. pete williams in washington, what have you learned? >> i was going to say what you lairpd from tom, other law enforcement officials saying police are no longer searching for any thought to be at large from today's shootings. the stand-downs and lock-downs and shelter in place orders l t lifted. it's about time for public schools to be let out for the day and all those lifted. it will be a normal, pretty much close to a normal end of the school day for students in montgomery county, maryland, suburb north of washington, d.c. the question is now going to be, why were these people shot today? what was the motive for the sho shooting? it's pretty clear what the motive is for last night's sh t shooting, based on what the police claim happened here was he was shooting his estranged wife in a custody dispute. the two victims initially shot in all these incidents were women. we have no reason to believe at this point that he knew any of the victims today. there were two vict

tom costello, thank you. let's bring back former ntsb investigator greg feith. we just saw him a moment ago. greg, there have been a couple cases of planes falling from the sky. there was air france 447 a couple of years ago, and malaysia flight 370 but those were attributed in part to what the pilots were doing in the cockpit. what makes this potentially more suspicious and what do you make of the sharp turns before it dropped off radar? >> when you look at air france 447, lester and of course, asia air, those airplanes were traversing bad weather so they stayed airborne for awhile before they got themselves basically because of pilot import or lack thereof into a situation that was unrecoverable for the pilot. in this instance, you have an airplane that's in a steady state cruising flight 37,000 feet and for whatever reason after normal communication, the airplane goes into a very high speed dive according to the radar information that was released. and it was making several, what they call, abrupt turns followed by a circular spiral turn that ended up in the

i agree with tom costello in a couple ever places. one, the track of the airplane having been so abruptly stopped almost and if they find the debris pretty much underneath that last radar position, that will lead investigators to look very seriously at the possibility of an in-flight breakup. this airplane type has been in service since the mid-1980s. it's a very proven design. it's very safe and has no history of in-flight breakups. now the question is what could cause that? and i think those are going to be central questions to the investigators. first we need to find the boxes, and we'll do that in pretty short order. >> john, let me ask you because if there was no human involvement in the seconds before whatever happened occurred, what i mean, if the pilots didn't call in a may day, didn't touch a switch that would have somehow automatically alerted folks that something was happening, if none of that happened, these black boxes, they are found because they turn themselves on in some way, the pinging. how does that happen? >> well,
