777 vanished more than three months ago with 239 people on board. joining me now is david susi, cnn safety analyst and former safety inspector for the faa. good to see you again, david. one of the big assumptions reflects a belief it s likely the pilots suffered oxygen loss. what combination of factors has to happen before that happens? there s two different possibilities here, fredericka. one is lost prez yourization in the cabin and not able to reduce the air flight speed and lower it to an area where they could breathe so that is a possibility number one, just that there was something that incapacitated them such as an explosion, decompression to cause a problem with the aircraft. secondly, could have been that the oxygen bottle itself was simply empty in the event and assumed they had oxygen and continued to fly.
airplane, malaysian airlines flight 370. keep in mind, this has been nearly four months since that plane disappeared, but we are now learning today that the jet s crew was probably unresponsive, suffering from oxygen deprivation. the plane, flying on autopilot for at least five hours. so let me just back a half step up. this report, issued by the australia transport safety bureau is suggesting the plane then ran out of fuel before spiralling into the ocean. so to our richard quest, our aviation expert, who has been all over this. richard quest. let s begin with let s begin with the pilots. because like i mentioned, the report suggests the crew was suffering from hypoxia or unresponsive for some other reason. explain the possible oxygen loss and what that means for the final hours of this flight. i m going to have to sort of slightly take issue. the report sort of puts that as a possible possibility, and a possible out there. basically says that
something you could prohibit. so effectively, unanimously, all nine justices today siding with these anti-abortion protesters who didn t like this massachusetts law. that law is unconstitutional. thank you very much. let s move on to some other news we re following including the hunt for flight 370. new developments today, flight 370 investigation officially shifting south into the uncharted depths of the indian ocean. the new zone unveiled by officials is pegged on new data analysis that makes assumptions about why it vanished more than three months ago with 239 people on board. joining us is our aviation correspondent richard quest. it s the likelihood they suffered oxygen loss. what could have caused that? what the report basically says and it s the first you
officials. this site is the best available and most likely place where the aircraft is resting. the search will still be painstaking. of course we could be fortunate and find it in the first hour or the first day, but it could take another 12 months. experts keyed in on the new zone by making critical assumptions what happened to the boeing 777. among them the pilots could have become unresponsive due to oxygen loss. also the plane flew on autopilot for at least five hours and glided as far as 20 nautical miles before spiraling into the sea. joining us is david, a former faa inspector and author of why planes crash. good to see you. it s interesting. i think the assumptions, the thing getting the headlines, the possible oxygen loss, it flew on autopilot, i want to be clear about something, they re not basing this on any evidence they found, any data they re getting from the planes themselves, like
