An F-16 fighter jet and a small plane have collided in midair over South Carolina, raining down plane parts and debris.
The fighter jet collided with a Cessna C150 at around 11am local time, the Federal Aviation Administration said. The collision happened about 11 miles north of Charleston.
It was not immediately known how many people were on board the planes and whether anyone survived. It was not known if anyone was hurt on the ground.
The US Air Force has flown F-16s since the 1970s, though very few active duty squadrons still fly them.
Many F-16s still in service in the US are assigned to Air National Guard units, but Colonel Cindi King, of the South Carolina Air National Guard, said the F-16 involved in the crash did not belong to the Guard.
Berkeley County Airport manager Stacy Thomas declined to comment on the plane crash, referring questions to the FAA.
An Air Force official said the pilot of the crashed F-16 has been taken to a base in South Carolina for observation.
Lt Jenny Hyden at Shaw Air Force Base did not disclose his condition.
