Beats the Nimrod lash-up
I flew on an R.1 not too soon after Operation Corporate and was really surprised at the air refueling lash-up. A flexible pipe ran from the overhead, at the end of the probe, down the wall at the back of the cockpit and into the floor. About 8 or 9 inches in diameter (not sure as this guess if from memory from 1982. In my response to how they managed to add them so quickly, the station commander said H.S. had engineered and offered the probe when the Nimrods were first developed but the Air Ministry did not take them up on the accessory. Even then, the R.1s had to add the strake under the aft fuselage to correct a nasty dutch roll tendency with the probe fitted.
Heck, even the a/r receptacle in the Rivet Joint would occasionally leak hydralic fluid. First indication would be a warm fluid dripping down the back of my flight suit. Never had an fuel leaks there.
