If you like Apolllo 13 as a choice, check out The Right Stuff, which I believe was about the Mercury program. After watching that flick, you’ll want to fly the biggest American flag you can get your hands on. I’ve never felt so proud to be an American from watching any other film. It’s long, around 3 hours l, but well worth it.
I've seen it many times and have a copy of the DVD. I also have a fairly well-worn copy of the book.
I get the distinct impression that Tom Wolfe was not particularly enamored of John Glenn and that Gordon Cooper was his favorite. LOL
