The crew of the Soviet Soyuz 11 spacecraft are killed when their air supply escapes through a faulty valve.
The entire crew of Soyuz 11 perished in 1971 when cabin depressurization struck during reentry, marking the only deaths in space.
On June 30, 1971, the Soyuz 11 mission ended in tragedy when a faulty valve caused rapid cabin depressurization during module separation.
Cosmonauts Georgy Dobrovolsky, Viktor Patsayev, and Vladislav Volkov were returning from the world's first space station, Salyut 1.
Because they were not wearing pressure suits, the crew lost consciousness and died before ground controllers could intervene.
The disaster prompted major design changes to ensure future crews wore protective suits and improved valve systems.
It remains the only human spaceflight accident that resulted in fatalities during spaceflight.
Soyuz 11's legacy shaped safety protocols for decades of manned space exploration.
