held by isis tonight. thanks so much for watching. hope you have a good weekend, anderson cooper with john berman anderson cooper with john berman starts now. -- captions by vitac -- www.vitac.com thanks for joining us. a lot happening tonight. developments out of southern iran where an airliner from due b buy was ordered to land. breaking news out of the caribbean. it concerns the small plane that took off from rodchester new york today and scrambled u.s. fighter jets when the plane stopped responding, ultimately flew past the destination in florida and crashed in the sea off north jamaica. on board a prominent rodchester couple, a big real estate developer and a big booster of this particular kind of french-made airplane. there was reports wreckage from

the plane had been found but that does not, repeat does not appear to be the case. just moments ago, we spoke by phone with a major from the jamaican defense force. give us the latest in the search efforts. >> like you said, the latest information i have, is we spotted an oil slick in the vicinity where we suspect the aircraft went down about 14 miles. >> an oil slick. any debris of any kind? >> the information i have, which was up to about 5:00 p.m., oil slick. the situation may have changed but unfortunately, i don't have that update. >> an oil slick. are you confident this oil slick is connected to this plane? >> we're fairly confident, yes,

sir. we're fairly confidenconfident. in fact, we have a search and rescue dive team now trying to carry out the -- well, at this point we're not even sure if it's going to be a rescue operation anymore, more like a recovery operation based on the length of time that the aircraft would have gone down. we do have aerial assets on location as we speak. >> will they work throughout the night, major? >> that's the problem. we have two -- we're going to have to suspend the operation as long as permissible given the conditions. but the plan is to resume at first light tomorrow morning. we're actually expecting a u.s. cutter to be providing some assistance, as well, expected to get here early tomorrow morning. >> tomorrow morning in audition to the u.s. cutter, what resources will have you have available to you at this scene

of this oil slick? >> we have committed one offshore patrol vessel. we also have two aircraft in the air, as well as 412 helicopter that does the transportation work. >> and as you said, there is no sign now of wreckage, but you have seen an oil slick. do you have any sense what type of wreckage you might expect to see in an incident like this? any reason to believe the plane is still in tact, perhaps under the water? >> well, given the depth of the water, it's really difficult to say. it's really difficult to say at this point. in audition to the depth of the water, there is also the search and rescue, the theory that we triangled where the aircraft most likely would have gone and that's fairly unpredictable given the size of the area and given the conditions.

it's very difficult to say what we will be able to recover. >> okay. major basil jarett, an oil slick to look at in the morning at dawn. we appreciate you being with us. thanks. >> you're welcome. thank you very much for having me. you heard it there, the search when it resumes tomorrow is proceeding in parallel with a search for answers. there may be much to learn from the timeline itself. rene marsh reports. >> reporter: a search mission underway for this smell plane which it crashed 14 miles off the coast of jamaica. it took off from new york around 8:45 this morning bound for nape -- florida. over north carolina the pilot told air traffic control there was a problem but did not declare an emergency. he was cleared to descend to

25,000 feet but asked to go lower. >> we need to descend to about 180. we have an indication that is not correct in the plane. >> stand by. >> 900 kn descend and maintain level. >> an hour and 15 minutes after take off, the pilot stopped responding. f-15s tracked it along the east coast of florida. one fighter pilot looked through the window. >> i can see his chest rising and falling. right before i left was the first time we could see he was actively breathing. >> the pilot was slumped over and the windows frosted, both are signs the pressure may have escaped leaving the pilot without enough oxygen to stay conscious. the aircraft flew over the bahamas. >> we have been in touch with the two countries in whose

flight space it went through, the bahamas and cuba. i don't have more details on those conversations but ob$=um1e1ñ this is an issue of security and safety so we're in touch, as well. >> 4.5 hours after take off, the plane crashed near port antonio, jamaica. >> rene marsh joins us from washington. rene, incidents like this are rare but not unheard of. there was a similar incident last week, correct? >> that's absolutely right, john. if this pilot suffered from hypoxia, it's not unheard of. similar situation this weekend. the faa lost contact with a private plane. it flew into restricted air space over washington dc and the pilot in this case, as well, unresponsive, did not respond to radio calls. fighter jets were scrambled. they tracked that plane until unfortunately it eventually crashed into the atlantic ocean

and then, john, there is the pain stort incident in 1999. the famous golfer and five others on board were killed when that plane crashed. the plane was actually flying for about 1500 miles, most of it, we believe, the pilot, co-pilot and passengers were apparently either unconscious of dead. so it flew for a very long time. >> i remember. rene marsh in washington, thanks so much. let's bring in a couple more experts. miles o'bryan and david soucie. miles, david a former faa inspector and author of "why planes crash, an accident investigator's fight for safe skies." miles, based on the fact the f-15 fighters could see a pilot slumped over and breathing by the prostfrosted windows, that highly likely there was a

decompression event? >> the evidence is put in that direction, john. you had a situation where he reported an indication that something was not correct, which is a vague statement, and then he requested a drop in altitude to 18,000 feet. there was not a lot of urgency portrayed in that radio transmission and it was kind of a muddled message, if you will, which would tell you something about perhaps someone sumping from hypoxia and euphoria. he might have been suffering from it when he made the call. the air traffic controller did not pick up on the signs. he was busy and did not get him down to a lower altitude, 18,000 feet quickly. >> hypoxia is lack of oxygen and leads to confusion? >> when you get above 10,000

feet the human body doesn't have enough air to survive. when you're at 28,000 feet, you have three minutes or so of useful consciousness and after that you pass out and what you saw unfold might happen. >> all right. david, this type of aircraft, the tbm 900, you say it can go as high up as 40,000 feet so how advanced is the pressure system? >> it's very advanced. it was just recently changed from 2014 that did a lot of work with improving the pressurization so they can get an two 1,000 feet. but the differential, pressure differential from the outside to the inside is really what they worked on a lot. there are different components not in last year's model. those are areas i would look at first with trying to determine what happened with this pressurization system, if indeed, that is what happened. >> you were just at a safety

course for this plane. can you tell us anything about the safety record? >> well, yeah, they had a pretty troubled history, actually, when it comes to the ability of private pilot to maintain and fly this sophisticated aircraft. there is a lot of loss of control-type accidents. the structure and integrity of the aircraft itself is reliable and always has been. the french military uses it extensively. it has a great history for structural and mechanical background but the pilot's ability to maintain and keep up, that's where they suffered a little bit. they started these safety similar narcoti seminars and they hired me to talk about safety awareness and being aware of the oxygen deprivation problem and what can happen within the range of flight, so it's -- we do a lot of work on that and i know mr.

glazer attended these seminars. he was not in my seminar in june this year, but he had been done to the training at simcon. he was aware. this highlights as miles was pointing out just how quickly hypoxia can sneak up. >> miles, the pilot did indicate there was a problem to air traffic control but did not declare an emergency or ask for assistance, you know, maybe it was the high pypoxia or what difference would it make if he said emergency? >> all of a sudden he owns the air space around him and all the traffic has to get moved out of the way. once you hear mayday or emergency, that plane owns that air space. so things would have happened dramatically differently if he used those words. of course, the catch 22 here is that because of the nature of the emergency, he may not have

been able to recognize it and call for it. >> miles o'bryan, david soucie, thank you for joining us. the search resumes tomorrow morning at dawn. a quick reminder, set your dvr to watch "ac 360" whenever you'd like. next, the breaking news on the flight with americans on board that was forced to land in iran. also tonight, new developments in the death of joan rivers. we'll tell you about early word from the medical examiner's office here in new york and what investigators want to know about the clinic where she stopped breathing.

more breaking news as the scramble to locate any survivors from that small plane got underway, another eave uatiavia story. a charter airline filled with contract workers leaving afghanistan are forced to land in southern iran. at the time, we neither knew how things would unfold or where they might lead, now we ,óobdo. tom foreman joins us with the very latest. what happened here? >> this was a strange story. the plane was taking off in afghanistan to fly over the tip of pakistan across iran to land in dubai. chief problem, it took off three

hours too late, and that became a problem when it hit the air space down here going into iran because the iranians at that point said this is too late. you're outside of your flight plan window. you must turn around and go back and the pilot of this chartered plane with these 100 american contractors on board said i don't have to fuel to do that. iran said you land here or we will force you down, john. >> so it's on the ground in iran, not where it wants to be, tom. what then? >> well, then what happens is the officials from dubai air, which operate this charter basically start having a meeting with the iranians and explaining. the iranians come on and look over the plane and check out the people on board, i'm sure, the plane itself to make sure they are satisfied to make sure there is nothing wrong and after they are satisfied with that, then they said this plane can go on, john. >> all right. we know it took off a short time ago. do we know if it's finally made

it out of iranian air space or back to dubai? >> they had to get a new crew, because the new crew was involved so long they couldn't keep flying. that took a delay. once they get the people in, the plane took off at 6:45 p.m. eastern time and we can bring up the message that came out of the state department saying yes, infect, it landed in dubai about 8:00 eastern time and no doubt, everybody on board is relieved and answering a lot of questions about precisely what happened with the iranians. a tense moment for awhile there, john, that seems to have ended okay. >> the end of an unexpected odyssey, thank you so much. president obama arrives home tonight after an especially high stakes moment on the global stage with russia threatening ukraine and isis on a bloody tear through iraq, the president had a two-fold mission at the nato meeting in wails. to meet challenges and clear up confusion in some corners and

out right doubt in others about his policy confronting isis. joining us now in wails, gyp acosta traveling with the president. jim, this seemed to be tougher talk than we've heard from the president lately on the issue of isis. this wasn't about making isis a manageable problem. >> reporter: that's right, john. this was a different president obama on this final day of the nato summit. you recall last week the president got in a lot of hot water, not only with republicans but democrats when he said he didn't have a plan to deal with isis and syria and said he wanted to reduce the threat to a quote manageable problem. he was much tougher on the threat earlier today. this is what he had to say. >> we'll degrade and defeat isil the same way we have gone after the al qaeda affiliate in somalia. you can't contain an

organization that is running rough through that much territory causing that much havoc displacing that many people killing that many innocents and slaving that many women. the goal has to be to dismantle them. >> and the president cautioned that this effort will take some time and even secretary of state john kerry added at a session today that the effort could take years, john. >> he said the effort will take a coalition and he announced a coalition, a core coalition of allies to fight isis. what more can you tell us about that? >> that's right. it's a coalition of ten countries at this point, ten including the united states. these countries will be doing different things based on their varying capabilities and appetite for direct military action in iraq and potentially syria but secretary of state john kerry and top administration officials like chuck hagel and the count terrorism advisor will go to the

middle east to line up air partners for this coalition and it's an effort and endeavor that the president thinks will be successful and ultimately help this mission have credibility on the world stage. >> this administration, jim, does still seem to be conscious or aware or under the belief that many people in the united states are war we'ary so how di administration today address that feeling? >> we heard the president say during his press conference that lasted 24 minutes, he was out quickly, that there will be no boots on the ground. there will not be a ground combat role for forces in iraq or syria and then secretary of state john kerry had interesting comments at a nato session during which he said that would be a red line for the united states in terms of having combat troops on the ground in iraq and potentially syria. of course, that term red line is not one that the white house would use because president

obama's red lines have been crossed in the past, but it does under line how serious the president is taking this pledge of having to combat troops on the ground. >> jim acosta in wails for us. thanks so much. >> you bet. much more on this story and others at cnn.com. just ahead, the exact cause of joan rivers' death still a mystery. tonight, the latest on the investigations that her passing has triggered. >> this is the egg arrival. the arrival. she was incubating is what she told us. >> i'm not going to say anything nasty. she came in an egg and some people will do anything to not have to speak to ryan seacrest. i was supposed to be one of the people, seriously, they asked me to walk around in the entra raj but i got fired after the first meeting. i said is it just me or am i the only one that thinks this is

in her hometown new york and in hollywood, joan rivers' fans

are paying tribute leaving flowers outside herma manhattan apartment and on her star of fame. the exact cause of her death is still unknown. today the medical examiner said an autopsy was inconclusive and more tests will be needed. what we do know is that for whatever reason, rivers stopped breathing and went into cardiac arrest at the outpatient clinic where she went last week for what is being described as an elective throat procedure. >> do you understand you would have something to talk about for the rest of your life. >> joan rivers joking about her death. >> i'm 81 years old, i can die any second. >> now multiple investigations into that very issue. an intense spotlight on what transpired. >> she said she was having a procedure on vocal cords or throat in the morning.

>> didn't seem concerned? >> no, not at all. >> jay had dinner with rivers the night before she went for an early morning in what should have been routine procedure. >> if a patient was going to yorkville endoscopy, would it be for anything other than a die justive issue? >> i spent many patients to them happy is for upper and lower endoscopy. >> so anything from acid reflux to ulcers? >> correct. >> a patient would typically be sedated with propofol. >> you call this a twilight, not fully under. >> twilight not so deep you need breathing controlled. you're actually breathing on your own. >> reporter: a camera connected to a tube inserted into a esophagus. tommy had one done at yorkville last year. >> this place looks like you're in a hospital in a professional

setting, and i think that that reassured me at the time that there wouldn't be any issues, and if there were, that they would be addressed right there. >> reporter: 10 million upper endoscopies are done every year but any time with said diedatioe is risk. >> you can have issues with the heart, a heart attack, the heart rhythm not working well that can lead to other problems or problems breathing. >> reporter: the new york state department of health and acrediting agencies have open investigation into yorkville endoscopy. the cause of death still unknown. the state department of health say there are no complaints or violations regarding this facility. the clinic has not responded to calls from cnn for comment. and now you're looking at a live picture of the space, the stoop just outside her upper east side

apartment here in new york. there are stunning orchids, beautiful, beautiful roses out there, sunflowers. i've seen a lot of these at memorials. i've never seen such beautiful flowers left for anyone, certainly fitting for the queen of comedy, john. >> i'm sure she would appreciate that. as of now, no known cause of death. any word when we may get that official statement from the medical examiner? >> reporter: we know the examination of the body has been done and that will be turned over to the family. it's the toxicology at that point. this is a very high profile case, obviously. they want to understand what happened. there are several investigations that hinge on what those toxicology reports come back with. it could be days before they get them back, depending how complicated, could be weeks, john? >> thank you so much. miguel marquez outside john rivers apartment. the procedure that joan rivers had, it's not uncommon,

neither are outpatient surgery clinics. there are almost as many of them as hospitals in the united states. i want to bring in dr. sanjay gupta. sanjay, in these types of outpatient clinics, is it always an anesthesiologist administering the anesthesia? >> not necessarily. when you talk about anesthesia, there are different things being done. if somebody is having surgery, for example, the throat which we presume, it could be a numbing spray in the back of the throat, medications that are more anti answerty or propofol or general anesthesia. there are people who are not anesthesiologists that take courses in sedation. they learn how to sedated someone. they can use the training to perform these procedures. we don't know if there was an

anesthesiologist present. there are none on the roster, if you will, at this endclinic. >> it isn't clear what anesthesia was used on her but propofol is commonly used. a lot of us know the name of this drug because of michael jackson's death. what do we know about it in its safety record? >> it's a medication used for a long time. it's medication that i use in my own practice and part of the attractiveness of a medication like this that obviously got people to know about it because of michael jackson but it's gotten a lot of use in terms of its very quick actions. it's able to come on very quick and go off very quick so a patient can go to sleep quickly and wakeup quickly and that's what you want, especially in settings where it's more of an outpatient-typesetting. i wanted to show you, john, what it looks like. we'll go inside the operating

room of how it works and what's necessary for it to work. >> we're here inside the operating room of a chief of anesthesia here. propofol is something he uses all the time. it looks like milk of amnesia. >> milk of amnesia. >> are you okay? we have to monitor his ecg and make sure he's breathing and make sure he's ventlating. >> reporter: that's all typical stuff. >> standard of care, yes. >> reporter: okay, so the propofol. >> you'll get sleepy. give me good, deep breaths. >> reporter: take a look at his eyes, how quickly. >> deep breath vincent, doing great. you may feel a little burning, okay? >> reporter: ten, nine, eight, seven, six, five, four, three,

two, one. you saw john what i mean how quickly a medication like that works but you also saw everything ahead of time. they were given oxygen and want to make sure one is preoxygen. the point is, john, even though it's a medication that's used quite a bit, there is a lot that goes into using a medication like that and that's why you want people trained doing it. >> lastly, sanjay, what type of resuscitation equipment is required to be on the premises at a clinic like this? >> the basics sort of really apply here and we talk about abc, literally, airway, breathing and cardiovascular, circulation. you want to be able to make sure if someone has problems with airway, we call it losing the airway because the throat swells, there is bleeding, something happens, you got to be able to secure the airways and

there are secertain things if someone has problems with blood pressure or heart problem to give them medicines or perform procedures to get the heart started again, everything from defibrillator to certain medications that increase blood pressure. i will tell you, john, there are tens of thousands of these procedures done in outpatient centers every year in the united states. most of them go without an absolute hitch, but you're zeroing in on a couple important points in terms of what exactly is required, what the accreditation means, do anesthesiologists need to be on stand by. some of those are more fuzzy in terms of the answers than i think we have realized. >> these are some questions that no doubt will be asked during these investigations. thanks so much for being with us. appreciate it. >> thank you. up next, the red carpet joan rivers that the world saw was one facet of a remarkable woman, that's according to her head writer at fashion police, head writer and close friend. rivers gave him his big break in

industrious always working, i mean always. as reported hours before having out patient surgery and suffering cardiac arrest she performed at a comedy club in manhattan and before she became famous, her show fashion police, she created a new comedy genre. >> she wanted to be noticed. this is -- >> that dress has more creases than my face before botox. this dress is the invasion of iraq and kirsty ally. her body is like the dark meat special at kfc, all thighs and no breast. that dress was so hot, she was sweating more than dean watching tory going through his phone. it's like hip-hop music, you

know what i mean? it started all black and sexy and now there's a bunch of white trailing behind it. >> fashion police announced a two-week hiatus. tony tripoli is the head writer. he worked closely with rivers on her material. they were more than colleagues. they had a close, close friendship and he joins me tonight. so tony, you first met joan rivers a little more than four years ago when she picked you to be the head writer of fashion police. that had to be an incredible moment. >> oh, oh, she changed my entire life in that moment. i was sort of asked to go and spend a day writing with joan rivers, of course, who will say no to that? after ten minutes, she goes i need to talk to you in the kitchen. i thought oh my gosh, this is my childhood hero is going to take me in the kitchen tell me i'm too dirty or too pushing or on

knox shows and to get out and we got in the kitchen and her little finger spun around and she said you're the new writer of "fashion police." i said come on, i have no credits, i'm some struggling standup comic. she said it's done. >> you said you grew up and she was your hero. when you finally got to meet her and work with her, was she like you thought she would be? >> no. no, because you see her on stage and she's this demon. she's, you know, prowling the stage like a tiger and she's just got that laser focus and she's, you know s, she's viciou in the best possible way and you think this is hilarious but this person wouldn't probably be super fun to spend time with, right? off stage, she's -- she was the most stereotypical jewish grandma you could ever meet.

she was forever holding your hand and telling you she loved you and she was always, you know, saying did she need a mint because she was always worried that, you know, she was going to have not perfect breath. like she was just always telling you to eat something and wanting to know why you haven't met a nice doctor. >> what's it like to write jokes with someone whose been at it, you know, for 50 plus years? by the way, at the top of the game. >> yeah, and she was never satisfied. she was grateful and would say these are great jokes, thank you so much and then she would sit there in the makeup chair and go over them over and she would say tony, how can we remove a word? this joke needs to have one less word and she would figure out which word to take out and suddenly the joke was ten times funnier. to her, comedy was math. >> i've heard you say the dirtier the joke, the harder she would laugh but still, there was

stuff you had to explain to her? >> we can't discuss on this show some of the names for sexual positions that i had to explain to this, you know, sweet 81-year-old woman, right? i had to -- she just, you know, there were certain rap lyrics that we might reference in a joke and she -- you know, this is not a woman who has gotten jiggy with it very recently. so she was -- what are you talking about? but if, you know, if i said trust me, you saying that this lady's outfit is really ratchet will get a huge laugh because nobody expects you to say the word ratchet, she would go okay, we'll try it and after the show she would take your hand and say thanks for making me do that. you're right. >> what will you personally miss most about her? >> she had the greatest laugh on earth, and most comedians always need to be the fun naeest person in the game and most comedians have this weird competitive thing around other people that

might be funny, right? they need to be the alpha. and joan loved nothing more than when someone would say something that laid her out. that was her greatest pleasure. it was -- and so when i would get to, you know, pitch her an idea for a joke, and she would throw her hands up and just go you're killing me and she would laugh -- i just -- it breaks my heart that i'm not going to hear that laugh again. >> well, it's a wonderful thing you got to experience and i think you're one of millions that will miss her so much. tony tripoli, thanks for being with us. >> thank you. joan rivers was frank about her cosmetic surgeries. someone posted a sign at a london train station saying as a tribute to the late joan rivers, parts of this station will be gradually replaced over the next 40 years. okay, maybe harsh but a good bet this would have made her laugh.

with everything else she did, what she wanted when she wanted it when it came to plastic surgery, even though in her own words, it terrified her. here is gary tuchman. [ applause ] >> reporter: joan rivers' comedy stood the test of time. >> 30 years old you're not married, you're an old maid is. a man is 90 and unmarried, he's a catch. >> i'm wearing the same under wear which everyone back stage remembers. [ laughter ] >> reporter: her unique style was consistent. less consistent, her appearance. >> my body is my temple and my temple needs redecorating. >> this is such a stupid elective surgery. >> no, no, no, it's elective but i bet each one of you would do something if i paid for it. >> reporter: joan rivers never hesitated to talk about her plastic surgeries.

back in 2007 she had a humorous heart to heart with jay filling in on "larry king live". >> when you first did it, joan, the plastic surgery -- >> i did it wrong. >> how old? >> 41. >> natural bags from my father and i was starting to get that tired 41-year-old look, you know, and i just thought let me do it now. somebody told me i look -- johnny's wives said do it before you need to. >> did you do it because you wanted to be prettier or felt you were looking older? >> i wanted to look better and of course you want to be pretty. everyone in society -- as i always said, no one asked eleanor roosevelt to dance. >> reporter: joan rivers talking about plastic surgery never failed to make audiences laugh. but jones' daughter melissa was clearly worried about her mother and her plastic surgeries. >> i have tried in every way possible to explain to you how frightened i am and how i feel

like this is an unnecessary risk. it turns out i'm not the only person with concerns. >> i don't understand this. >> everyone feels the same way -- >> feels the same way what? >> we just don't want to lose you. >> oh, for god's sakes, you're all in the will. >> joan rivers herself acknowledged having anxiety around procedures. >> aren't you scared -- >> terrified. >> it's very risky. >> very serious. my dad was a doctor. the anesthesiologist is as much a part of that group as the plastic surgeon. very serious. but you also want to be in a society that wants people to look good. >> she did not let anxiety stop her. >> look good, look good, look good. i spit on education. did you go to college? tell us how it helped you now. [ laughter ] >> and we laughed with her about it for decades. gary tuchman, cnn, atlanta. >> a quick program note at 10:00

when it's full. more importantly, it's a reservoir storing water piped into homes and for agriculture helping to grow much of the nation's fruits and vegetables. john took us on a boat to see the shoreline and it's even more astounding up close. the lake seems more like a narrow river. the drought has created a canyon, a hillside of rock that's normally covered by water. the water level is down by more than 200 feet. it's a common site throughout the state, most of california's major reservoirs are less than half full. >> what would we see? >> the water up probably half way up the hillside at this time of the year. >> reporter: more than 80% of the state is either in the extreme or exceptional category, the highest levels. it's meant no showers or running water for several communities

and increase in fires. brown and neglected public parks and farmers losing crops. >> it's like mourning. it's dead. our product is dead. it's just -- we cannot sell it. we have to knock them down. >> reporter: jesse grows table grapes and estimates he'll lose 40% of his crap this year due to the drought. with low reservoirs, farmers are pumping water out of the ground and if there weren't pbad enoug and there is new research that says it could destabilize the san andre fault and cause earthquakes. the changeuñ in pressure can cae those quakes. >> earthquakes are these mysterious things that happen under our feet. so having a way for people to cause these earthquakes to

happen is unsettling. >> reporter: experts say the quakes would be small and unlikely to cause damage, still, another example why this drought is causing stress to the land and the mental well-being of almost an entire state. >> those are stunning, stunning pictures. we'll be right back. i make a lot of purchases for my business. and i get a lot in return with ink plus from chase. like 50,000 bonus points when i spent $5,000 in the first 3 months after i opened my account. and i earn 5 times the rewards on internet, phone services and at office supply stores. with ink plus i can choose how to redeem my points. travel, gift cards, even cash back. and my rewards points won't expire. so you can make owning a business even more rewarding. ink from chase. so you can.
