There was movie I saw, back in like the early 70's. The story line was a prisnor of war camp along the German/Swiss border or German/Austrian border. The POW's build a glider and launch it from the ridge of the top floor roof, using a tub that is dropped from several stories to provided the accerlation power to lauch the glider. The glider glided into friendly territory carrying a very import person. Any ideas? Can't remember who played in the movie as I was very young at the time. But, would love to find the movie.

Could it possibly be 'son of lassie?'

Son of Lassie (1945)

Sounds like The Birdmen

It is the Birdman. I just read your link. Thanks so much. I saw this movie once when it came out in 71. I was ten then, and have always wanted to see it again. Hopefully I can know find a copy. Thanks again.

You're welcome.
