I’m sad to say that the crash of the Yemenia flight outside of Comoros doesn’t really surprise me. I have heard various horror stories about how that airline is run and some of the things that have gone on from people on flights. Planes hitting things on the runway as they took off and passengers being seated in the cockpit being some of the more egregious examples. If this kind of thing goes on in sight of everyone, I can’t imagine what goes on (or doesn’t go on as the case may be) behind the scenes.
Bottom line? Don’t fly Yemenia.
