Some basic miniature work in this film. Mostly shots of model aircraft against a rear projection screen, sometimes with some foreground mist moving past. There is a crash sequence with a miniature landscape, the wing breaking off on impact. Some miniature work is also used in the rear projected backgrounds through the windows of the interior cockpit set. There are no credits listed for the miniature work.
If anybody recognizes what the aircraft are that are represented by the miniatures in the film please let me know in the comments.
The entire film can be found on youtube.
