The "Phillips report" was a document summarizing a review conducted in November–December 1965 by a NASA team headed by Lt Gen Samuel C. Phillips, director of the Apollo manned Moon landing program, to investigate schedule slippage and cost overruns incurred by North American Aviation, manufacturer of the Command/Service Module spacecraft and the second stage of the Saturn V launch vehicle. Phillips sent a summary of his findings with a strongly worded letter to NAA president Lee Atwood demanding corrective action be taken. North American revised its management of its Apollo contract items, and NASA management considered the matter a normal part of confidential agency-contractor relations.
