Three Navy crew members died when their EA-6B Prowler crashed Monday morning about 50 miles west of Spokane, Washington, the service said.

The Navy has yet to release the names of the three service members.

The plane crashed at about 8:45 a.m. PT, sometime after it took off for a training flight from Naval Air Station Whidbey Island in northwestern Washington.

The crash is under investigation, according to the Navy.
