that blasted NASA for failing to properly store data from older space missions like the early Mars probes. We'd spent millions flying those missions and the primary product was the data. According to the GAO, NASA had put the data (stored on magnetic tapes) in some pretty bad places where the tapes were degrading. Worse, they didn't have the telemetry decommutation schema available so all the tapes appeared to hold was random data. You have to know how the telemetry stream is structured in order to retrieve and process the data. NASA/JPL refuted the GAO report, quite well IMO.

As for the movie "Battlefield Earth", I never saw it. Perhaps that's just as well.
