A US Air Force helicopter made an emergency landing in Virginia after it came under fire, injuring one of its pilots, while the FBI opened an investigation.
The US Air Force said in a statement that the "UH-1N" was flying 10 miles northwest of Manassas, Virginia, on a routine training mission at an altitude of 1,000 feet when the accident occurred.
The preliminary results indicated that the helicopter was hit by a bullet that resulted in a slight injury to one of the crew members, and damage to the plane.
An Air Force official said the plane landed safely at Manassas Regional Airport, west of Washington, D.C., and the pilots were taken to hospital where they were treated and left.
CNN pointed out that the incident is now under investigation by the FBI and the Air Force. An official said the plane would be closely examined for other damage.
