AGUILA, Ariz. (AP) - Authorities have identified a man who was killed while piloting his glider plane in the desert northwest if Phoenix.
Maricopa County Sheriff's spokesman Christopher Hegstrom says 61-year-old Robert Knauff died Saturday afternoon after his glider crashed to the ground in Aguila.
Hegstrom says Knauff was about 100 feet in the air when a towrope connecting him to an airplane somehow became disconnected.
Witnesses told investigators Knauff appeared to try making a sharp turn and then the glider plane stalled, hitting a pole.
Knauff was pronounced dead at the scene.
Hegstrom says Knauff, a retired Army major general, was the registered owner of the aircraft.
There were no other injuries.
Aguila is about 85 miles outside of Phoenix.
