Two United Airlines planes clipped wings at Dulles International Airport on Thursday afternoon.

Airport personnel responded at about 2:30 p.m. to a report  that two flights had clipped wings, said Rob Yingling, a spokesman for the Metropolitan Washington Airports Authority, which manages Dulles and Reagan National Airport.

The two planes involved were both United aircraft, the airline confirmed to The Washington Post. United flight 951, arriving from Brussels, clipped the wing of a United plane parked at a nearby gate.

The passengers and crew exited the Brussels flight normally; there were no passengers on the parked plane.

“Our maintenance team is evaluating both aircraft to determine any damage,” according to a statement from the airline.

Dulles personnel and airport firefighters responded to the scene and did not find any initial damage, fuel spills or other hazards, Yingling said.

Personnel and firefighters remain on the scene, and the Federal Aviation Authority has been notified.

Several photos were posted to Twitter that showed the two wings touching:
