Pen Hadow.......Aviation expert??
I think the real problem here is that Pen Hadow is an A*se ! and that the media love these kind of Terror stories
The descent was well executed and conformed to standard aviation practice. I would agree tho that there is an argument for making it clearer in the safety announcements that in the event of decompression the aircraft will descend steeply and rapidly.
The sad truth is that pax too often pay little attention to the safety brief. The problem is that if we say it like it could/will be then we would frighten the passengers to death before even taking off!
