A D.C. taxi flipped on its roof at Reagan National Airport Thursday evening.

It’s unclear how the accident happened nor whether anyone was injured. Fire department and airports authority spokespersons were not immediately available for comment.

Photographer Erinn Shirley said she encountered the scene while traveling on the Mount Vernon Trail around 8:30 p.m. Her photos show a tree knocked over by the crash, a tire tread under a “Welcome to Virginia” sign and one or two luggage-toting travelers standing near the wreck.
