On November 14, 1969, at 11:22 a.m. ET, Apollo 12 with NASA astronauts Charles "Pete" Conrad, Alan Bean, and Richard "Dick" Gordon blasted off on there Saturn V Rocket. Lightning struck there Saturn V launch vehicle just 36.5 seconds after launch and again at 52 after launch. Several systems were knocked out. The fuel cells disconnected from the Saturn V's power, a number of external sensors were lost, and power failed to the system that relayed the spacecraft's data to both the crew and Mission Control.
