Always problematic refuelling a C-130. Because the VC10K HDU when fitted with the normal drogue was very difficult to set up at the low speed needed to refuel the C-130 and the hose would often run in and put the brake on as soon as the probe touched it....
Fitting a low speed drogue worked OK and we had a procedure for extending flap and slat to fly at around 180-200KIAS at FL200 with the centreline hose trailed. But the tanker fuel burn was colossal!
