Photograph number P-10063A
On August 13, 1969 six Apollo astronauts (Bean, Carr, Conrad, Gibson, Irwin, and Scott) visited JPL and were briefed in building 179 about the Surveyor 3 lander that would be found on the surface of the Moon. In preparation for removing the camera and other spacecraft parts, several of them attempted to cut a piece of structural aluminum tubing and found that tin snips were inadequate for the job.
