DENVER (AP) - Investigators say a radio-controlled model airplane was outside its designated flying zone when it collided with a full-size biplane at a Colorado airport last year.
The National Transportation Safety Board's final report released Thursday says the model operator's actions caused the collision.
The collision occurred Aug. 14 during a model airplane show at the Van-aire Estates Airport in Brighton.
The NTSB says the biplane landed safely and no one was injured. The biplane was substantially damaged and the model was destroyed.
The report says the lack of a formally designated spotter at the event contributed to the collision.
It says the biplane pilot had aborted a landing attempt and was preparing to circle for another attempt and the model was attempting an escape maneuver at the time of the collision.
