// Quote I am saying that given the elements I have today, I can only say that he deliberately allowed the loss of altitude. It's not a loss that is totally abnormal, 1,000ft per minute; but he had no reason to do it, or not to allow captain in to cabin, he had no reason not to explain to air traffic control why he was losing altitude
The theory that he had a health attack? Apparently he was breathing normally, so this is not someone having a heart attack, for example.
I think that the victims only realised what was happening at the last minute and I think that he voluntarily refused to open the door and turned the button to bring the plane down. //
