Shuttle's Flight Recorder Found

The Orbital Experiment Support System starts recording data to a tape 10 minutes before re-entry. The OESS is unique to the shuttle Columbia and was used in early shuttle missions to verify predictions on design. It records temperature readings, aerodynamic pressure, vibrations, strain, acceleration and rates of pitch, roll and yaw. The OESS is possibly the "golden nugget" the investigators of the Columbia Accident Investigation Board have been looking for.

NASA has been using models to try to understand the Columbia’s reentry. By removing leading panels on the wing, investigators have approximately reproduced some of the thermal data from Columbia.
