Milt Windler, a NASA flight director best known for his role in helping bring the Apollo 13 crew home safely after an onboard explosion crippled the spacecraft in 1970, has died at age 94. Windler was one of the key mission control leaders whose quick decision-making during the crisis became emblematic of NASA's "Failure is not an option" ethos. His death was marked by tributes from the space community recalling his contributions to the agency's early human spaceflight era. He is remembered as part of the generation of flight directors who helped define NASA's mission control culture during the Apollo program.
