North American Rockwell completed an investigation, requested by NASA, of the Apollo 12 flight anomalies associated with apparent vehicle electrostatic discharges at 36.5 and 52 seconds into the flight.

The investigation indicated the most logical recommendation consistent with cost and schedule considerations to minimize or eliminate similar occurrences was for more restrictive launch rules. When atmospheric conditions exhibited electrostatic gradients in excess of several thousand volts with severe fluctuations or when heavy cloud conditions associated with frontal passages existed even in the absence of precipitation or reported spherics activities, delay of launch should be considered.
