Two Boeing 777s clipped wings at Washington Dulles International Airport on Thursday afternoon.
United Airlines Flight 951 was moving into position at Gate C-12 when one of its wingtips hit the wingtip of an empty plane parked at Gate C-14, said an FAA spokesperson.
The passengers on Flight 951 -- which had just arrived from Brussels -- deplaned without incident. No injuries were reported.
The Metropolitan Washington Airports Authority is investigating the incident.
