• NASA launched the uncrewed Apollo 6 from Cape Kennedy at 7:00 a.m. as the second test flight of the Saturn V launch vehicle. The rocket propelled a mockup of the 28-ton CSM (Command/Service Module) and the 17-ton Apollo Lunar Module into earth orbit, but the premature shutdown of two second stage engines and the overcompensation of other engines put the vehicles into an altitude "110 miles too high" and consumed most of the fuel that would have been necessary to propel the craft out of Earth orbit and to the Moon. "If the Apollo 6 had carried men," an AP report noted, "a mission to the moon would have been aborted."^[26] The craft re-entered the atmosphere almost 10 hours after its launch; the USS Okinawa (LPH-3) recovered it in the Pacific Ocean.^[27][28]

Plaisted, Walter H. Pederson, Gerald R. Pitzel and Jean Luc Bombardier (employed by Bombardier Inc. as a technician to service the Bombardier snowmobiles) arrived at the top of the world at 2100 UTC (3:00 p.m. in Minnesota).^[98] In later years, as historians came to doubt that Robert Peary's expedition had actually reached the North Pole on April 6, 1909, a historian would note that although "most of the media considered Plaisted's trek more of a stunt than the actual achievement that it was... it was Plaisted, the amateur explorer and insurance salesman from Duluth— and not Robert Peary— who was first to reach the Pole over the pack ice."^[99]
