The Space Shuttle
The shuttle, a manned, multipurpose, orbital-launch space plane, was designed to
carry payloads of up to about 30,000 kg (65,000 lb) and up to seven crew members
and passengers. The upper part of the spacecraft, the orbiter stage, had a
theoretical lifetime of perhaps 100 missions, and the winged orbiter could make
unpowered landings on returning to earth. Because of the shuttle's designed
flexibility and its planned use for satellite deployment and the rescue and

was destroyed about one minute after launch because of the failure of a sealant

hole in the main propellant tank of liquid hydrogen and oxygen and caused the
booster to nose into and rupture the tank. This rupture caused a ...
