Pegasus bomber
Alright Tim,
Keep your hair on, I was right it was some sort of V-bomber ( tis' a long time since I had the photo's ).
When the Harrier GR5 appeared, it had the feature of 'hot refuelling', ie filling up on the ground without shutting down the engine.
A test pilot got a bit carried away one day when in a Sea Harrier, and requested hot refuelling - snag being on the Harrier 1 series the refuelling point is aft of the forward nozzle !
To his credit ( ? ) the groundcrew chap did try, before backing off hastily.
