A US Navy jet crashed nearby Mount Rainier in Washington state and a search was underway for the plane's two crew members, the Navy said.
The EA-18G Growler aircraft crashed east of Mount Rainier Tuesday afternoon during a routine training flight, the Navy said in a statement.
As of Tuesday evening, the status of the crew members was unknown, the Navy said. Their identities were not released.
The plane was based at Naval Air Station Whidbey Island in northwest Washington.
Multiple search and rescue assets were launched from the air station on Tuesday for the search operation.
Heavy snow and patchy fog were forecast for Mount Rainier on Wednesday, according to the National Weather Service. Between 2 and 3 inches of snow was possible.
The Federal Aviation Administration has issued a no-fly zone around the search area, CBS affiliate KIRO-TV reports.
The cause of the crash was under investigation.
The downed aircraft is part of Electronic Attack Squadron 130, which boasts of being the oldest electronic warfare squadron in the Navy.
According to the squadron's website, the EA-18G Growler's sensors and weapons “provide the warfighter with a lethal and survivable weapons system to counter current and emerging threats.”
Last December, a Navy surveillance plane overran a runway at a military base in Hawaii and plunged into Kaneohe Bay, but all nine on board were unharmed.
