shed light on why this happened. we re also not showing any faces in the frame. in addition to three guests who will be joining us shortly, all experts in aviation and crash investigations, they will be weighing in on what they see in this video. because whatever brought the flight down on approach yesterday to nepal s second largest city likely happened or became unstoppable in those seconds that you ll see. 72 people were above the twin engine european made airliner, at least 68 are known to have died. now, the last video is difficult to watch. the plane in the sky. we should warn you again so is this video inside the plane. the view is out the left side of the aircraft. you see the wings trailing edge. the back side of the wing as the plane starts to bank to the left. in a moment you ll see a white flash where we do an edit. then the plane levels momentarily and then just a few seconds later, it all goes wrong and the plane banking again drops. take a look. we have live re
of course that did not come into play here that i can see. it s so difficult and tragic to watch this, anderson. you can get some information from those videos. but the other thing i noticed from those videos and mary and les had said is that left flap is up higher than you might normally see during approach. the only thing that i can think of, the amount of kinetic energy that is required to make that aircraft bank so quickly is a lot. there has to be something in the air flow or as les mentioned a possible stall. but if that left flap was split, we call that a split flap condition, in which one flap goes lower than the other, it can cause a very dramatic roll because that s a lot of mass out in the air flow to make the aircraft go one direction or the other. of course it s too early to speculate, but this tragic situation, as i said, it s after being on accident sites and going through it, it s quite emotional to have to go through that and see that. but it s necessary. david, do y
soundsound is okay. important for you to hear or investigators to hear to get a sense if people onboard knew anything was wrong. let s just play that again . david, the plane that crashed was an atr-72. can you talk about that aircraft? it has kind of a sordid history with regard to icing and all things that have happened all the way back to 1996. that model has had some difficulty with icing.
one of them happens to be the unfortunate video that you see inside the cabin. to me, the configuration of the airplane is interesting. it looks like only part of the flaps or partial flaps are down. in other words, they were just initiating the approach configuration. what it says to me is that possibly this airplane got too slow for that configuration and it induced an aerodynamic stall potentially. why that happened, it s hard to say. i mean it s possible mary mentioned something about all the engines being operating. it s hard to hear in that audio but it s possible if they lost an engine, they might have added too much power on one side being slow and it might have started that roll and eventually aerodynamic stall. david, before i go to you, i want to play that video again from inside. i want to play the audio and just confirm with our translators that people are not panicking so we think the
we have live reporting and a team of experts. ivan watson in hong kong, an aviation analyst is a former transportation inspector general, also cnn safety analyst and former faa safety inspector, david sousi and the retired american airlines captain and co-host of the candid cockpit podcast. i want to go to ivan watson for the latest reporting. what do we know now about this plane crash. reporter: we know the plane was an atr-72 twin engine turbo prop. it was only supposed to be flying a 25-minute flight and the last communication was about 18 minutes into the flight. it crashed into a deep gorge not far from the airport. we ve seen this video filmed by
