The Space Shuttle That Fell to Earth

As Nasa prepares space shuttle Columbia for its 28th mission, excitement and trepidation build amongst the astronauts and their families. But a month before they are due to launch, Nasa grounds its entire shuttle fleet when cracks are discovered in the fuel lines.

Nasa engineers spot a piece of debris striking the shuttle during launch. In space, the crew continue their mission, unaware of the concerns, but the clock is ticking to re-entry.
