As the lead man on Grumman Aerospace’s Environmental Control and Life Support (ECLS) Group, I helped develop, test, and verify the Lunar Module ECLS. I was deeply involved in ECLS Mission support work and was the only recipient at Grumman of a signed trophy (a large engraved mug) from the first lunar landing astronauts for my mission support work. I also worked continuously for 48 hours in Mission Support during the troubled Apollo 13 Mission, and played a key role in saving the astronauts on Apollo 13.
