This week marks the 40th anniversary of the final Apollo mission, Apollo 17. Eugene Cernan, Ronald Evans and Harrison (Jack) Schmitt blasted off for the Moon on what was to be a hugely successful and record breaking mission. The launch, however, was delayed by 2 hours and 40 minutes. The delay was due to a minor technical error which caused an automatic cutoff in the launch sequencer during countdown at T-30 seconds. The launch auto-sequencer failed to pressurise a 3rd stage tank and then failed to recognise that this had been manually pressurised. Lift-off finally took place at 05:33 GMT on 7 December 1972.
