Tell me I'm wrong but has Pan Am set some record by appearing in two full length feature films under it's own name.
I refer to "2001, A Space Odyssey" and "Catch me if you can". "2001" features a hostess wearing Grip Shoes to assist her in zero gravity. There is a very close close-up of the shoes with the Pan Am logo.
None of the pseudo airline stuff like "Transglobal" in "Airport".
