BOAC--
I sat in 20F again on the flight back this afternoon, and although it looked like a slightly newer 200 (trim inside a bit more modern) there was again a steady burble of oil from the seams at the back of the engine. (Oh, and smoke from underneath, as advertised.)
Now I know it's normal, I suppose I should start to worry if it's not there... still not impressed with the 'excess fuel' brush-off. I'm English, dammit. I'm *used* to ancient machinery leaking oil.
