MONTVILLE, Maine (AP)   A summer camp owner in Maine says a small plane crash crashed as it dropped candy from above on campers.

Hidden Valley camp owner Peter Kassen tells the Bangor Daily News that the so-called “candy drop” is a 40-year-old tradition.

A fixed-wing, single-engine Cessna crashed into trees at the camp July 3 after an aerodynamic stall and left three people aboard injured.

Kassen says the pilot and two passengers were taken to a Belfast hospital, which released them later that evening. The rural town of Montville is located about 50 miles (80 kilometers) southwest of Bangor.

Federal authorities are investigating the crash.

Kassen said no aircraft will be involved in future candy drops.
