I recall reading a couple of incidents concerning early Bucc AAR:
One naval aviator was pottering about in an S1 at a reasonable rate of knots when he noticed a switch. But couldn't remember what it was for - he assumed it was for screen washing. So he operated it, there was a rumbling noise and to his surprise the retracted probe appeared, wobbled briefly, then bent round and departed the fix....
Another chap decided to have a go with the newly-fitted fixed probe. He found an agreeable tanker, went astern and was cleared for contact. Which he achieved fairly easily. The tanker duly announced 'fuel flowing', but the Bucc's looker didn't see any of the fuel gauges increasing. So they assumed something was U/S, disconnected and returned to land; the looker grumbling that the radar wasn't working. After they'd handed the cab back to the groundcrew, the chap folding the radome found it almost impossible to move. But he persevered and duly folded it - whereupon a couple of hundred pounds or so of fuel gushed out. It seems that the probe had been fitted, but the mod. had yet to be completed, so it hadn't been connected to the fuel system - hence the Blue Parrot had been treated to a kerosene bath....
