The eagle bearing Apollo 11 patch is, of course, the most famous of all space mission patches. Several, besides the Apollo 11 crew of Armstrong, Aldrin and Collins, contributed to its creation. The back-up to Neil Armstrong, Jim Lovell, suggested a bald eagle as the symbol of America. Collins sketched the initial version of the eagle on the patch adding the Earth overhead. Though the appearance of the scene was edifying, several errors existed in the astronomy. The sunshine came from the wrong direction so that the terminator line was vertical with respect to the lunar scene instead of horizontal. A simulator instructor name Tom Wilson suggested the eagle carry an olive branch as a message of the peaceful nature of the mission.
