An Early Technicolor film directed by William A. Wellman who directed a lot of aircraft related films. Most of the aircraft action in the movie employs actual full size aircraft with a few miniature exceptions. There are a couple of montage sequences that show the development of aircraft through the years that are depicted using models against a painted sky background. There is also a ditching at sea and a subsequent rescue using an amphibious aircraft which also is done in miniature. Miniature effects supervised by Gordon Jennings.
