Investigators are trying to figure out what caused a small plane to crash during an air show in Wisconsin killing the pilot.
Witnesses say there was a puff of smoke and then the plane spiraled to the ground.
It landed in a wooded area in Stevens Point, Wisconsin away from the air show crowd.
No one else was injured and the pilot’s name has not been released.
Police canceled the rest of the show.
The NTSB is investigating.
