Not exactly an RAF brevet story perhaps, but a pretty amazing story of an extremely hazardous wartime flight of which I had certainly never heard - regrettably in the form of an obituary:
Kazimierz 'Paddy' Szrajer - Telegraph
An amusing "tailpiece" - or should that be "codpiece"? - following the cutting of the brake lines to free the Dakota's wheels reads: "Because its hydraulic fluid had bled away, the undercarriage could not be retracted. The pilot’s report merely stated that the reservoir was recharged
“with all available fluids” until sufficient pressure was obtained to permit the undercarriage to be pumped up by hand."
