And if the actual U2 pilots (air force pilots and CIA operatives) had come back profoundly changed, someone might have cancelled the programme...

Astronauts are regular smart people capable of making good and bad life decisions too.

I met someone a couple years ago who was a U2 pilot (which are still in active service). He'd flown F-16s until he reached the point in the promotion ladder where flying stopped, then switched to U2s to keep being a pilot. After hitting 20 years, he was taking his retirement and training to fly Grumman S-2Ts with CAL FIRE.

Very down-to-earth guy who knew what he wanted and made his choices. Didn't at all seem like the sort to find edge-of-the-atmosphere flying a mystical experience.
