Lockheed L-1011-385-3 TriStar K1 (500) airtanker RAF - Eastern Express
The Royal Air Force operated nine L-1011-500s TriStars, six ex-British Airways and three ex-Pan Am.[2] The TriStars were bought in the immediate aftermath of the Falklands War to bolster the long range capability of the RAF in the transport and tanker roles, as the demands of refuelling Hercules supporting forces stationed in the Falklands was rapidly using up the fatigue life of the RAF's Handley Page Victor tankers.
