With the passing of John Glenn last week, I thought it would be appropriate to pause my coverage of Apollo 10 for a week and create an episode that celebrates the life of the American Icon, John Glenn. I covered John Glenn’s Mercury flight in episodes 30-31. I am going to re-release those episodes over the next 2 days. So I won’t spend a lot of time on his Mercury flight in this episode, that will be covered tomorrow.
Had it not been for the fact that Eisele damaged his shoulder during a zero-G training flight aboard a KC-135 aircraft just before Christmas 1965, he might have been in the senior pilot’s seat aboard Apollo 1, instead of Ed White.
What went wrong? Even years after the investigators began to sift through the wreckage of Apollo 1 piece by piece, no one could say exactly. But within weeks the general picture became clear: The fire was a disaster waiting to happen.
Mercury-Redstone 4 was the fourth mission in the Mercury-Redstone series and the second U.S. manned suborbital spaceflight. The mission was essentially a repeat of Alan Shepard’s Freedom 7 flight. So why was it necessary to launch another sub-orbital mission? Why not proceed with an orbital flight to match the Soviet Vostok 1? Among other things the U.S. needed more space experience to corroborate the “Man-in-Space” concept. Also the Redstone was the only booster NASA had that was approved for manned launches. The Atlas booster was available but not ready. Atlas was capable of putting a Mercury Capsule into orbit, but it had been launched three times with unmanned capsules, and it had exploded on 2 of the 3 attempts.
