Did you get that idea from Top Gun?
I miss Goose.
Years ago I toured the NASA facility at Moffett Field. They had a U-2 (plus one they were cannibalizing), and we were allowed to see inside the cockpit. It was VERY rudimentary. The seat was made out of wood. I did not know it had any ejection capacity at all.
After the infantry, I went to the airforce and was an aircraft mechanic, f-18, Chinook, griffon, snowbirds etc. I’m quite familiar with the systems, and that just seemed the logical explanation.
Also, yes it happened in the movie Top Gun heh.
IIRC, Gary Powers ejected from his U-2 at very high altitude over the Soviet Union. We were stunned when he was captured alive because we didn’t think ejection was survivable from that altitude.
