immediately after the fire in 1967, nasa followed its established procedure of investigating and identifying corrections for the cause, with presidential and congressional oversight. no one in nasa's upper management expected that the phillips findings would be printed as a document, but this had been done and on february 13, bergman was shown a copy at the office of manned space flight headquarters. he then told a junior senator on the aeronautical and space sciences committee, walter mondale, about the document, and later reported its existence on abc. mondale proceeded to grill the top managers, including webb who was completely blind-sided (the formal review had not gone above seamans), about the report's existence. other senators, such as margaret chase, then questioned webb about nasa's choice of north american as the apollo contractor.
