1981-073A
FLTSATCOM F5 was launched in Aug 1981 from Cape Canaveral. The orbit was more eccentric than planned. It was positioned at 73W for tests, but its antenna failed to deploy. The satellite was not used operationally but it was stored in GEO until 1986. A failure review concluded that the spacecraft support adapter had structurally failed, causing the satellite to hit the inner skin of the Atlas Centaur nose fairing, damaging the spacecraft.
