Ok I saw it late one night years ago. I am going to say late 50s early 60s.
I thought it was a Tony Curtis movie, with George C Scott, but it may have been others since I can not find it in either’s filmographies.
It started with these two pilots flying F-86s sabers in Korea, and the followed the two of them for the rest of their Careers, I think a love triangle may have been involved and the main char was not as successful as his buddy.
Anyone have a clue?
