I imagine they would try to avoid it, except in emergencies. In the particular video shown, it might be possible to track down the flight and find out if there was any emergency involved.What, you don't believe they do this?
What, and give up my chance to impress my 'friends' with my erudite remarks?Facebook is bad news in any case Jerry. #DeleteFacebook
