The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA), as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development.^[10] The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. Five complete Shuttle systems were built and used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida.

Vastag betuvel kiemelve. Ez nagyon nem heti 1 repulse, es az elso is csak 1981-ben.

Olyannyira lehetseges volt SS-rol bombazni 1977-ben, hogy 1981-re sikerult felloni az elsot!!!!!
