A privately operated Murphy Renegade Spirit, a single engine biplane, was en route from Trier-Fonren Airport Rhineland when it crashed, seriously injuring the pilot.
The pilot apparently had difficulty in the air and attempted to return to the airport. He made a precautionary landing en route back to the airport.
A Luxembourg Air Rescue medevac helicopter flew him to a hospital.
The plane was written off as a total loss.
