2 Planes Crash Mid-Air At Wings Over Dallas Show: FAA

DALLAS, TX — Two planes collided mid-air during Wings Over Dallas, a World War II airshow taking place Saturday at the Dallas Executive Airport, according to the Federal Aviation Administration.

The crash involved a B-17 airplane and a Bell P-63 Kingcobra, the FAA said. It's unknown how many people were on either aircrafts.

Graphic video shared to Twitter captured the collision, showing a smaller plane crash straight into a bigger aircraft followed by debris flying in the air. A massive explosion can then be seen on the ground with thick flames and smoke rising from the scene.

Witnesses told NBC Dallas-Fort Worth that a wing came off one plane as it made a pass over the airfield. Debris was also reported on Highway 67, according to WFAA.

The airshow was scheduled to take place Nov.11-13.

The FAA and the NTSB will investigate the crash.
