Two World War II-era military planes collided in midair and crashed Saturday afternoon at Dallas Executive Airport, killing everyone on board.

The B-17 was part of the Commemorative Air Force's collection, nicknamed "Texas Raiders," and was kept in a hangar in Conroe, Texas, near Houston.

The B-17, a mainstay of American air power during WWII, is a massive four-engine bomber used in daylight raids against Germany.

Several social media videos showed the fighter plane flying into the bomber, causing them to crash to the ground and igniting a large ball of fire and smoke.

There were no reports of injuries on the ground, but Dallas Mayor Eric Johnson said the debris field from the collision included parts of Executive Airport, Highway 67, and a nearby strip mall.
