Radar forensic data from the U.S. Civil Air Patrol indicated that at approximately 3:18 p.m. Thursday, the plane experienced a sudden and rapid loss of altitude and speed, Coast Guard Lt. Cmdr. Benjamin McIntyre-Coble reported. “What that event is, I can’t speculate to,” he said.
McIntyre-Coble said that no distress signals had been received from the aircraft. Planes are equipped with an emergency locator transmitter that, if exposed to seawater, transmits a distress signal via satellite to the Coast Guard. However, no such signal was detected.
All 10 people on board were adults, and the flight was a routine commuter service, according to Alaska State Troopers Lt. Ben Endres.
With most Alaskan communities off the main road network, air travel is often the only viable option for long-distance transportation, particularly in winter. The area is known for unpredictable snow squalls and high winds.
This incident is the third major U.S. aviation disaster in just over a week. On Jan. 29, a commercial jetliner and an Army helicopter collided near Washington, D.C., killing 67 people. Two days later, on Jan. 31, a medical transport plane crashed in Philadelphia, killing six on board and one person on the ground.
