He was promoted to Spacecraft Team Manager, and in this role he directed over 100 engineers, technicians, and quality control specialists in the ﬁnal assembly, integration, and ground test of the Apollo 11 LM-5 Eagle. The LM-5 was the first spacecraft to land on the moon and return the astronauts to the mother craft in lunar orbit. Mr. Fleisig’s last years at Grumman were spent as Advanced Systems Engineering Manager for US Air Force space trajectory software and helicopter systems development. Mr. Fleisig ended his career as a private consultant, serving US and German aerospace concerns.
