MONTEBELLO, Va. (CBS19 NEWS) -- The Federal Aviation Administration confirms that a small plane, a Cessna Citation, crashed near Montebello, Virginia, around 3:30 p.m. on Sunday.

According to sources, this was an unresponsive business plane that flew over Washington, D.C. Sunday afternoon. U.S. military F-16 fighter jets chased the plane, causing a loud sonic boom, which was heard in D.C., Virginia and Maryland. 

Pilots of the F-16s say that the Cessna pilot was passed out and that the plane was unresponsive.

The FAA says that the Cessna took off from Elizabethton Municipal Airport in Elizabethton, Tennessee, and was on its way to Long Island MacArthur Airport in New York.

The plane then turned around, flying over the Capitol, before crashing in the mountainous region near Montebello.

Search efforts are ongoing and VSP says that troopers are unable to fly the area because of fog and low clouds. The FAA and the National Transportation Safety Board are also investigating.
