Apollo 7's crew—Wally Schirra, Donn Eisele, and Walt Cunningham—reentered Earth's atmosphere without wearing helmets, despite Mission Control's warnings about cabin leaks, rapid depressurization, and landing impacts.
Notes on verification
Confirmed by multiple independent sources including History.com, Planetary Society, NASTAR Center, and Astronomy.com, detailing the crew's refusal to wear helmets during reentry against Mission Control's wishes due to concerns about sinus congestion and eardrum rupture, despite risks of depressurization.
