Four men disappeared when a twin-engine Cessna 310C vanished on October 16, 1972, en route from Anchorage to Juneau. Among the passengers were U.S. House Majority Leader Hale Boggs, Alaska Congressman Nick Begich, a Begich aide Russell Brown, and the 37-year-old pilot Russel LeRoy Brown (identified in some reports as Don Jonz). The flight left Anchorage about 9:00 a.m. into marginal conditions that included turbulence, rain, and low visibility; the last known position was near the Malaspina Glacier in the Wrangell‑St. Elias mountains, after which the aircraft disappeared without a trace.

A 39-day search involving the Coast Guard, Navy, Army, Air Force, Civil Air Patrol and civilian volunteers covered thousands of square miles of mountains and glaciers but found no wreckage, debris, or signs of the occupants. The official air search was suspended November 24, 1972, and all four men were declared dead on December 29, 1972. The NTSB later said there was insufficient evidence to determine a probable cause, and the disappearance remains unsolved.

If anyone has information about the flight, the plane’s last known whereabouts, or sightings in that area on October 16, 1972, please share what is known.
