WARSAW, Poland —  Two small planes collided during an acrobatic display at an air show in Poland on Saturday, killing both pilots, authorities said.

Footage broadcast on TVN24 television showed the two small red planes slamming into each other and bursting into fragments at the Radom Air Show.

Both pilots died in the crash, Polish Air Force spokesman Maj. Wieslaw Grzegorzewski said.

There were no reports of injuries among those on the ground; the television footage showed the collision happening well away from the crowd.

Recovery efforts were under way, and all events planned for Sunday were canceled, Grzegorzewski said.
