AGUILA, AZ - The Maricopa County Sheriff's Office says a man died when he crashed his glider in the desert northwest of Phoenix.
MCSO spokesman Christopher Hegstrom says the accident happened Saturday afternoon in Aguila.
Hegstrom confirmed Saturday night the victim was Robert Knauff, a retired major general. The aircraft is registered to an address in New York where Knauff had been commander of the New York Air National Guard .
According to witnesses, an airplane was taking the glider into the air when the towing rope somehow became disconnected.
Hegstrom says the glider pilot was about 100 feet up and made a sharp turn, falling to the ground.
There were no other injuries. It was not known how many people were on board the airplane towing the glider.
Hegstrom says the area is popular with air gliders.
Aguila is about 85 miles outside of Phoenix.
