KSC-69P-579. The NASA caption to this picture reads: “Apollo-11 commander Neil A. Armstrong descends the ladder of the Lunar Module Training Vehicle during practice for his upcoming lunar landing mission.” In response to an August 2003 e-mail, Neil wrote, “I really don't have the foggiest idea of what I was doing. I don't think it had anything to do with simulation. If I were simulating a mission phase, I would have the helmet on and suit pressurized. On the other hand, if it was only 5 days before flight, I would not be wearing the suit unless it was for a purpose.” 11 July 1969. Scan by Ed Hengeveld.
