The 1955 Hawaii R6D-1 crash was an accident involving a Douglas R6D-1 Liftmaster of the United States Navy which crashed into a mountain peak in Hawaii on 22 March 1955, killing all 66 people on board. At the time, it was the worst crash involving any variant of the Douglas DC-6 airliner[1][2] the second-worst aviation accident in U.S. history,[1] and one of the worst air accidents anywhere in history,[2] and it equaled the 11 August mid-air collision of two United States Air Force C-119G Flying Boxcars over West Germany and the 6 October United Air Lines Flight 409 crash as the deadliest air accident of 1955.[3] It remains the worst air disaster in the history of Hawaii[4] and the deadliest accident involving a heavier-than-air aircraft in the history of United States naval aviation.[5]
