I have started a webpage that will collect appearances of gliders in TV
programs and movies:

So far I have five movies on the list, with more to come. I know of the
following:

Escape From New York
Dawn Flight
The Sky Trap
Skyward
The Birdmen
Everybody Wants to Rule the World (music video)
Freefall: Flight 174
The Longest Day
The Boy Who Flew With Condors

I would appreciate pointers to any others you know of.
