The first Skylab prime crew-Charles Conrad, Jr., Dr. Joseph P. Kerwin, and Paul J. Weitz-and backup crewmen Russell L. Schweickart, Dr. F. Story Musgrave, and Bruce McCandless, II, began the 21-day preflight isolation period at 8:30 am EST in preparation for May 15 launch. Isolation would continue for seven days following their return from Skylab. Crewmen would be restricted to specific areas and limited in the number of approved personal contacts allowed durĀ­ing the immediate preflight and postflight periods. During the isolation only Skylab food and water would be consumed by the crew members. This diet would also continue for 18 days following the return from the mission, to obtain baseline data for Skylab medical experiments in nutrition and musculoskeletal evaluation series.

National Academy of Sciences' handling of the controversial supersonic transport was criticized by Philip M. Boffey, Managing Editor of the newsletter Science & Government Report and former Science magazine writer, in a report he released after a two-year "evaluation" study of NAS. The Washington Post later quoted the report as saying an NAS group in 1965, had "incredibly" urged the Government to conduct a campaign to persuade the U.S. public to accept the SST though it had 'become evident that the aircraft would produce harmful sonic booms. In 1968, NAS had downplayed the possibility of physical damage from the booms, though it later circulated a "clarifying" statement internally to its own members saying the SST would be unacceptable.
