The aircraft landed with a few bumps, with some witnesses saying sparks came off the front of it.
The passenger, John Wildey, said of the experience: "I suppose it was a controlled crash, really."
He added that he could not reach the brakes at first and thought he would not make it, but eventually managed to stop the plane.
Rob Murray, one of the flight instructors, said he was glad to have helped and that Wildey did a "remarkable job," given he had never flown a plane before.
"It's a fantastic feeling, knowing I have achieved something and probably saved somebody's life," Murray said.
Wildey was unhurt. Police said an inquest will be carried out to establish what caused the pilot's death.
