Space Shuttle Shuffle - S1.E3

Catastrophe beckons when gears controlling a Single Point of Failure Space Shuttle landing system are installed backwards. And, with the $50 Billion International Space Station running out of supplies, mounting pressure from world space agencies, and NASA attempting to Return to Flight after the tragic loss of Columbia, a shocking discovery that could have destroyed the Shuttle during launch causes NASA to cancel the historic launch, pull the Space Shuttle off the launch pad and "de-stack" for only the eight time in 30 years.
