A military aircraft from Naval Air Station Whidbey Island crashed in Eastern Washington on Monday morning, and the fate of the crew was not immediately known.

The E/A-6B Prowler was reported to have crashed about 8:45 Monday, Whidbey Island officials said.

Mike Welding, an information officer for the base, said he had no information on the crew, only that they were on a routine training mission. Prowlers typically carry a four-person crew.

Whidbey Island officials said the cause of the accident is under investigation.

Lincoln County officials are reporting that the crash occurred in a rural area near the towns of Harrington and Odessa.

NAS Whidbey Island is home to the U.S. Navy's tactical electronic warfare squadrons. Crews from the base, located on Puget Sound, regularly fly across Eastern Washington for training exercises.
