The Phillips report was a document summarizing a review conducted in November–December 1965 by a NASA team headed by Lieutenant General Samuel C. Phillips, director of the Apollo crewed Moon landing program, to investigate schedule slippage and cost overruns incurred by North American Aviation (NAA), 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.
After a fire killed the entire crew of the first crewed Apollo mission Apollo 1 on January 27, 1967, a United States Senate Committee on Aeronautical and Space Sciences hearing overseeing NASA's investigation of the accident led to the public disclosure of the Phillips Report by then junior Senator Walter Mondale, who was told of its existence by ABC News reporter Jules Bergman, who had seen a copy at NASA's Washington, DC Office of Manned Space Flight headquarters.
