At least two congressional representatives appear to have been aboard one of the planes. There were no initial reports of injuries.

ARLINGTON, Va. — A routine day at Reagan National Airport turned tense Thursday when a plane on the runway “bumped into” the wing of another aircraft, according to U.S. Congressman Nick LaLota, who was onboard during the incident.

The Federal Aviation Administration will investigate after two American Airlines regional jets bumped wings at Washington’s Ronald Reagan National Airport Thursday. “The wingtip of American Airlines Flight 5490 struck American Airlines Flight 4522 on a taxiway… around 12:45 p.m,” the FAA said in a statement.
