Eiermann lived in Cocoa Beach, Florida at the time of Apollo 15, and was a local representative of Los Angeles-based Dyna-Therm Corporation, which was a NASA contractor. According to Scott's autobiography, one night several months before launch, the astronauts' supervisor, Director of Flight Crew Operations Deke Slayton, had Scott and the other crew members come to dinner at Eiermann's house; Scott described Eiermann as a longtime friend of Slayton. Worden, in his autobiography, agreed that the crew was invited to dinner there, but described Scott as inviting his crewmates, and did not mention involvement by Slayton. In his testimony before a congressional committee in 1972, Scott described Eiermann as a "friend of ours", someone with whom he had dined and who knew many people at KSC, including a number of the astronauts. Scott also told the committee that he had met Eiermann at a party, rather than through another astronaut.
