In the aftermath of the disaster, Joe Shea resigned as manager of the Apollo project. Robert Gilruth, the director of the MSC, offered the position to Borman, who turned it down. The job was given to Gilruth's deputy, George Low; Borman accepted a temporary posting to the North American Aviation plant in Downey, California, where the command modules were made, to oversee the implementation of the recommendations of the AS-204 Accident Review Board. Borman was forced to confront one of the root causes of the disaster: the natural tension between getting the job done on time and building the spacecraft as well as possible.
