On February 1st, Columbia began re-entry as planned, but the heat shield was compromised due to damage sustained during the initial ascent. The heat of re-entry was free to spread into the damaged portion of the orbiter, ultimately causing its disintegration and the loss of all on board.

Columbia was delivered to the Kennedy Space Center in March 1979. Two years later, April 12, 1981, it lifted off from the Kennedy Space Center to become the first shuttle to fly in orbit.

The crew of its final voyage were 3 Mission Specialists; David Brown, Kalpana Chawla, Laurel Clark, a Payload Specialist and Commander; Ilan Ramon and Michael Anderson, Shuttle Commander; Rick Husband, and Shuttle Pilot; William McCool.

Arlington National Cemetery is the home of a Columbia memorial which is dated and has an outline of a Shuttle.
