Two vintage military planes collided in midair on Saturday at a World War Two commemorative airshow in Dallas, federal officials said, crashing to the ground before exploding into flames.
It was not immediately clear how many people were injured or killed.
The incident early on Saturday afternoon involved a World War Two-era Boeing B-17 Flying Fortress bomber and a Bell P-63 Kingcobra fighter that were flying at the Wings Over Dallas Airshow at Dallas Executive Airport, the Federal Aviation Administration (FAA) said in a statement.
