🚀 73 SECONDS - LIVE ON TV - 7 ASTRONAUTS DIED

January 28th, 1986. Kennedy Space Center, Florida.

Space Shuttle Challenger. 7 astronauts. Including a teacher.

*Christa McAuliffe.* 37 years old. First civilian in space.

Teacher in Space program. 11,000 teachers applied. She was chosen.

Millions watching live on TV. Children in classrooms. Families at viewing area.

11:38 AM. Liftoff. Beautiful. Perfect.

*73 seconds later. Explosion.*

External fuel tank exploded. Shuttle disintegrated. Y-shaped smoke trails.

*7 astronauts died. Live on television.*

But: *Engineers had warned.*

*Bob Ebeling and Roger Boisjoly.* Morton Thiokol engineers.

Night before launch: Teleconference.

"Don't launch below 53°F. O-rings will fail in cold."

Temperature morning of launch: *36°F (2°C). Coldest launch ever.*

Management ignored warnings. Schedule pressure. Politics. Image.

*Launch approved.*

Bob Ebeling told his wife: "Tomorrow Challenger will explode. 7 people will die."

*He was right.*

O-ring failed. Hot gas leaked. Hit fuel tank. Tank exploded.

*Crew cabin fell intact. 2 minutes 45 seconds.*

Investigation found: *3 PEAPs activated.*

Personal Egress Air Packs. Emergency oxygen. Manually activated.

Meaning: *At least 3 astronauts were conscious during the fall.*

They knew. They fell. They couldn't do anything.

Hit ocean at 200+ mph. Instant death.

Most tragic detail: *They didn't die instantly in the explosion.*

*Rogers Commission investigation:*

Richard Feynman's famous demonstration. O-ring in ice water.

Showed live on TV: Rubber stiffens in cold. Simple proof.

Conclusion: *O-ring failure + Management failure.*

*Preventable tragedy.*

Shuttle program stopped 32 months. Redesigned. Safety culture changed.

1988: Flights resumed.

But: *2003 - Columbia disaster. 7 more dead.*

Engineers warned about foam strike. Management said "no problem."

*History repeated.*

Shuttle program ended 2011. Two disasters. 14 astronauts lost.

Teacher in Space suspended. Barbara Morgan (Christa's backup) flew 2007.

*40 years later (2026): Still remembered.*
