At the time, it is the worst accident involving any version of the Douglas DC-6, and it remains the worst air disaster in the history of Hawaii and the deadliest heavier-than-air accident in U.S. naval aviation history.

The United States Navy attack transport USS Bayfield (APA-33) rescues the 19 survivors about two hours later.

Deadliest crash
Three crashes may claim the joint title of 1955's deadliest plane crash; two of these cases involved military aircraft. The first took place on 22 March, when the 1955 Hawaii R6D-1 crash, involving a United States Air Force Douglas DC-6, took place in mountainous terrain of Oahu, Hawaii, U.S., killing all 66 people on board. The second took place on 11 August, when two USAF Fairchild C-119 Flying Boxcars collided during a training formation near Altensteig, West Germany, killing all 66 people aboard both aircraft. The third, and the deadliest civilian aircraft case of 1955, took place on 6 October, when United Air Lines Flight 409, a Douglas DC-4 which crashed into Medicine Bow Peak near Laramie, Wyoming, U.S., killing all 66 people on board.
