The funny thing is they were supposed to leak fuel (JP-7). Considering how much the airframe stretched from heating, there was no way to seal the fuel tanks so the leak when cold. That’s also why the skin of the wing was corrugated so it wouldn’t crack. Once they hit cruse and the airframe heats up the leaks seal themselves. If you look at the photos of the SR’s approaching the tanker, if you can see the fuel leaking on the top of the wing, they have just taken off and are topping off the fuel load. If the wing is dry then she’s been at cruise and the tanks are sealed.
They used the fuel to cool various parts of the airframe and as hydraulic fluid for the engine exhaust nozzle. Also, the jet carried nitrogen in liquid form to blanket the fuel tanks with an inert gas to prevent a fire at operating temperatures.
Hi guy, did you know a B-52 crashed at barksdale loaded with nuclear bombs on board, ,in the area , I found the area when I and some friends were hunting deer on the base,we came up to a very high bobed wire fence about 15 feet high, and the wire had grown into some of the trees, this was 1970, their were radiation signs all over the fence. any way little known things about our old air force..

It's at the museum at Eglin AFB.
