RAF jets scrambled from Lincolnshire base to escort a plane with communication difficulties into an airport.
A plane from Bucharest was escorted into Birmingham airport by the fighter jets.
The private plane, which contained three crew and no passengers, was met by two Typhoon jets scrambled from RAF Coningsby, Lincolnshire, and a Voyager aircraft launched from Brize Norton, Oxfordshire.
They escorted the Saab 340 plane once it entered UK air space, Birmingham Airport said.
Its runway was closed for about half an hour while the freight-carrying plane landed just after 7.30am.
