Well, I don't know what will happen now... But it really doesn't matter with me now, because I've been to the mountaintop."
• On the same day, at the request of Mayor Henry Loeb of Memphis, U.S. District Judge Bailey Brown issued a temporary restraining order to prohibit King's plan to lead a march of 6,000 men through Memphis on April 8.

At 6:01 in the evening, King was preparing to go to dinner with his associates and was walking back into the room to get his overcoat. At that moment, Ray allegedly fired a single shot from a .30-06 rifle, and the bullet struck King in the neck. King was rushed to St. Joseph's Hospital and pronounced dead at 7:05. The powerful figure, described as a weapon of non-violence, died at the age of 39.^[21][22][23]

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 recovered it in the Pacific Ocean.^[27][28]

The AAP, Mathews declared, contained sufficient flexibility so that it could be conducted in harmony with available resources: "We are also prepared to move forward at an increased pace when it is desirable and possible to do so." He said contingency planning left room for both budgetary and mission goal changes, thus answering congressional criticism that NASA had not provided sufficient flexibility regarding long-term goals.^[19]

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).^[97] 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."^[98]
