The Marines were flying a routine training mission from Creech Air Force Base near Las Vegas to Miramar Air Station in San Diego when the helicopter crashed. The cause of the crash is still being determined but the area was experiencing turbulent weather at the time of the accident.
The helicopter was first reported overdue at 1:00 a.m. Wednesday and Cal Fire was notified at 2:20 a.m. Military and civil authorities launched a search of the Pine Valley, California, area, hampered in their efforts by snow and rough terrain.
The helicopter was located on Wednesday and the crew confirmed dead on Thursday.
The CH-53E Super Stallion helicopter has an accident rate roughly twice that of other helicopters used by the Marines. The heavy-duty aircraft is primarily used to transport supplies and is capable of lifting up to 16 tons.
CH-53Es have been involved in other crashes in 2014, 2016 and 2018, with two of those crashes fatal to all on board.
