The “age of Apollo” comes to an unbreathable end in an incident during the return of the final Apollo spacecraft. Returning from their successful Apollo-Soyuz Test Project flight, astronauts Thomas Stafford, Deke Slayton and Vance Brand are exposed to fumes from their vehicle’s own reaction control thrusters, thanks to the thrusters firing after the capsule’s air vents open during descent toward the Pacific Ocean. Brand reportedly passes out momentarily due to the toxic fumes. All three astronauts are hospitalized for two weeks in Hawaii.
