Low budget thriller about a new secret aircraft made out of plastic. Richard Arlen plays the test pilot whose job it will be to fly the aircraft on it's first flight. Don Castle plays Arlen's brother and one of the designers of of the plane. Of course there needs to be a sub-plot where the two brothers fall out over the same woman. Also standard to these films is the comedy relief supplied in this case by the company mechanic. Nothing great but for fans of early 40's aircraft it is a must see with several somewhat rare aircraft. What I found interesting about this film is that it is an early film from John Alton. Alton is well know to film-noir fans as perhaps the best director of photography of that genre. He also won an Oscar for "AN American IN Paris". Again, if you have an hour to kill and are into vintage aircraft then this is for you.
