Plane Crash Movie On My Flight

I watched a movie about airplane crashes on a recent flight.  A Yank in the R.A.F. was on TCM (free DirecTV in United first) and it was full of plane crashes and fires. In the old days when airlines picked their movies, they avoided ones with sensitive topics. It was a good propaganda film from 1941 (filmed in the UK with the Luftwaffe in the area), so I didn't notice it was about airplane failures until the end.

The funniest part of the movie was in the opening credits:
The Producers wish to express their appreciation to the officers and personnel of the Royal Air Force whose cooperation, under difficult conditions, made possible the filming of the aerial scenes in this production.

UPDATE: I also enjoyed North By Northwest and Von Ryan's Express on flights, so I guess prop plane crash movies are OK to watch on flights.
