Two helicopters hit each other in mid-air collision during a police exercise. The Bild newspaper said “one of the pilots was killed and four people were injured, two of them seriously injured”.
Footage showed the two aircraft on their side in the snow. About 400 federal police officers were conducting a football violence training exercise when the crash happened.
“Three helicopters were in the air. It was a real snowstorm. Suddenly we heard a bang and someone shouted ‘everybody down’”.
