The Unluckiest Satellites - Earthquakes, Rockets and Clogged Pipes

There's a series of failed rockets in 1990, 91 and 92 which were all linked together by their payloads, boosters and root causes. The Superbird B and BS-2X satellite ended up on the same booster due to bad luck, the booster was flawed due to a mechanic's error, which would have been caught if he hadn't fallen ill. The backup of BS-2X was also destroyed due to engine problems on Atlas-Centaur AC-70, but a rushed investigation meant the root cause was missed leading to a repeat on AC-71.
