Two pilots escaped without serious injury after their gliders collided, the ambulance service has said.
The wreckage of the two aircraft was found near Snailwell in Cambridgeshire, near Newmarket on the border with Suffolk.
One of the pilots parachuted to safety but the other was briefly unaccounted for after police and paramedics were called at about 4pm.
Lorna Marsh, spokeswoman for the East of England Ambulance Service, said both casualties had now been found in a field on the east side of Newmarket gallops.
She added: "One sustained no injuries and the other was initially unconscious but regained consciousness and did not suffer any traumatic injuries. That patient was taken to Addenbrooke's Hospital by land ambulance."
A Suffolk Police spokeswoman said they understood there had been a glider competition taking place in the area when they were called to the scene.
"We were called just before 4pm to a call that a parachute had been seen coming down near Snailwell in Cambridgeshire," the police spokeswoman said.
"There was a report two gliders had collided. It would appear he (the parachutist) was one of the pilots.
"Both gliders have been found in Cambridgeshire."
She said an air ambulance was at the scene with land ambulances and that the Air Accidents Investigation Branch had been informed.
