A small vintage plane, part of a fly-over demonstration, was already on the ground when it tipped over.
The main runway at Reagan National Airport was closed during the investigation. Auxillary runways were being used so planes are still able to arrive and depart the airport.
The main runway was reopened at noon and all flights were back to normal.
A crane was brought in to upright the plane.
Washington Post reporter Ashley Halsey was aboard the plane that crashed.
