Milt Windler dies at 94: the NASA flight director who was part of the Mission Control effort that brought Apollo 13’s crippled spacecraft home died Thursday, Oct. 1, according to CollectSPACE. He was 94. Ars Technica, citing a brief online notice, reported that Windler died surrounded by family.
Windler was the lead flight director for Apollo 13, but its recovery was not a one-man performance. He was one of four flight directors whose teams worked around the clock after an explosion in the service module crippled the spacecraft and vented its oxygen supply, according to CollectSPACE.
Before the accident changed the mission, Windler’s assignment as lead flight director covered the launch and planned lunar-surface activity. During the emergency, he and Gerry Griffin, the director of Gold Flight, asked controllers to develop three options for firing the lunar module’s engine to steer the spacecraft toward Earth, Ars Technica reported.
What was Milt Windler’s role in Apollo 13?
Windler led one of the Mission Control shifts and was Apollo 13’s lead flight director. His role in the emergency was part of the collective work by four flight directors and their controller teams to revise the mission after the explosion, rather than the original plan to conduct a lunar landing.
NASA Administrator Jared Isaacman described Windler in an Oct. 3 tribute as a Maroon Flight director who helped guide Apollo 8 around the Moon, played a critical role in Apollo 13’s safe return, and continued working through Skylab and later programs.
A career from recovery operations to the space station
NASA named Windler a flight director in 1968 after he worked on recovery operations during the Mercury and Gemini programs, according to Ars Technica. He later directed shifts for Apollo 8, the first crewed mission to orbit the Moon; Apollo 10; Apollo 12; Apollo 14; and Apollo 15. He also served as a flight director on all three crewed Skylab missions.
Windler said in a 2006 oral-history interview with the University of North Texas that the Apollo schedule left little time to absorb events as they happened. “You’d do a mission and then you’d immediately turn around and get ready for another mission,” he said.
Skylab brought a different operational problem. Windler recalled that controllers needed a way to revise plans in real time when solar activity created new requests from the science team. The system used planning cycles: science staff identified their goals, then a designated coordinator set objectives for the following day.
After Skylab, Windler worked on the space shuttle program and the development of the remote manipulator system, better known as Canadarm. After retiring from NASA, he joined private industry to work on operations and verification procedures connected to what became the International Space Station, Ars Technica reported.
Born Jan. 10, 1932, in Hampton, Virginia, Windler earned an aeronautical-engineering degree from Virginia Tech in 1954. He worked for the National Advisory Committee for Aeronautics, NASA’s predecessor, served four years in the Air Force, then returned to the agency’s Langley center before moving to Houston. His career formed part of the broader Mission Control effort behind Apollo 13’s recovery and decades of subsequent U.S. human-spaceflight operations.
