And yet another picture.
I like this picture because in May of 1965 I was stationed at Redstone arsenal on the other side of the hill from this test, and I probably heard the rumble and watched the mushroom cloud come up over the hill, as often occurred then. At one time, probably in 1964, I had the opportunity to stand on top of that very test stand.
41-second test firing of all five engines of the Saturn V S-IC stage, May 1965
This second picture was taken on that day in 1964.
