Senator Glenn was famous for attracting the fire of antiaircraft guns as a fighter pilot and for guiding one spacecraft into our atmosphere so as to avoid becoming a great ball of fire. Later evidence indicated the maneuvers weren’t needed because the instrument signal about the status of the heat shield was wrong. BUT, nobody knew that at the time.
On top of everything else despite being a human guinea pig/test pilot he lived to the ripe old age of 95. Now that’s protoplasm. But more importantly, that was the hand of God.
