Two vintage World War Two-era planes have collided and crashed at an air show in the US state of Texas, killing at least two.
Footage shows the aircraft striking each other at a low altitude, breaking one of the aircraft in half. A fireball can be seen as it hits the ground.
The planes – one of them a Boeing B-17 Flying Fortress – were taking part in a commemorative air show near Dallas.
It was not immediately clear how many people were in the two aircraft.
The Allied Pilots Association, which represents American Airlines pilots, said Terry Barker and Len Root – two of its former members – were among people who died in the collision.
Eyewitness Chris Kratovil – who was one of between 4,000 and 6,000 who had gathered to watch the Wings Over Dallas Airshow said he had “never seen a crowd grow more quiet or more still in just a blink of an eye”.
“It went from being a fairly excited, energetic crowd… to complete silence and stillness, and a lot of people, including myself, turned their children towards them and away from the airfield because there was burning wreckage in the middle of the airfield.”
