===OEX/MADS "black box"===
One unique feature that permanently stayed on ''Columbia'' from [[STS-1]] to [[STS-107]] was the OEX (Orbiter Experiments) box or MADS (Modular Auxiliary Data System) recorder. On March 19, 2003, this "black box" was found slightly damaged but fully intact by the [[U.S. Forest Service]] in [[San Augustine County]] in [[Texas]] after weeks of search and recovery efforts after the [[Space Shuttle Columbia disaster]].
