James Irwin
In 1980 I was living in Switzerland and went with a friend to a *conference featuring James Irwin. We went early but found that the place was packed. People were already sitting in the aisles. I suggested that we sit on the floor at the front but my friend said that his eyesight could not deal with being so close. So I made a route through the middle row expecting to be sitting in the middle aisle. Almost at the aisle we found a man with his coat covering two seats, when asked he said that he was trying to save them but his pals had not turned up. So we got seats in almost the centre of the auditorium.
We saw footage from the chest mounted camera while the astronauts drove the lunar buggy! Totally amazing!
Mr. Irwin explained that part of the mission was to find some white rock that the geologists had predicted would exist. The problem was that everything was covered with a grey dust. On their last day they had prayed to God that they would find it. Driving up the side of a hill they saw a large boulder, on top of which was a white rock, dust free! Mr. Irwin pulled a white rock from his pocket and then admitted that it was a NASA copy :)
At one point he also did the "blue marble" speech, I kid you not, when he held up a blue marble the audience was completely quiet.
Totally fecking amazing!!!
Mr. James Irwin was a brilliant orator. During the Q&A at the end he never once umed or ared but after a moments deliberation always gave a clear answer. RIP brave man.
