MIAMI (CBSMiami/CBS Local) — Today marks 33 years since the Space Shuttle Challenger disaster.

The accident on Jan. 28, 1986 — just 73 seconds into flight — killed all seven on board, including schoolteacher Christa McAuliffe.

The Challenger disintegrated over the Atlantic Ocean, off the coast of central Florida, after a booster engine failed. People all over the country watched the disaster live because the shuttle was carrying McAuliffe, who would have been the first teacher in space.
