Interesting in what way I wondered? Isn't this just the straightforward tale of FGP that is well known?
He didn't activate the self destruct and allegedly talked far too much and far too freely once safe. He handed the Sovs the entire package. He screwed the pooch. How could he expect to be "popular" on his return? I remember at the time my Dad saying that as the U2 was considered untouchable pilots were not given counter-interrogation training which was the only reason he was not courtmartialed and banged up for life tho I was too young to understand.
I suggest you read Gary Powers' book, might just enlighten you a little. You sound quite judgemental considering it wasn't your arse in a sling.
