Burbank Airport a filming location ??
I notice one of the filming locations was Warner Brothers Burbank Studio.
Judging by the mountain range in the background, it sure looks like the dive sequences with the Grumman F3F might have been filmed at Burbank Airport. It's a favorite spot for filming then and today, near to the studios. NCIS-LA has filmed a number of episodes there as well when an airport is required..
I flew into Burbank a couple years ago and the scenery looked real familiar.
