Royal Air Force of Oman 111s
The one that was converted was done, allegedly, on the whim of a senior British Officer on secondment as Commander Armed Forces. He didn't like tech stops en route to UK. The resulting a/c was great for him but did not have enough hold space remaining, for the luggage of the 80 or so passengers who could still fly on it when it was on non-VIP duties. All right for some!
