I missed the Spitfire, so I don't know how high it flew, but the Hurricane sound from no more than a couple of hundred feet or so was among the two or three most impressive of my life. Both planes have V12 Rolls-Royce Merlin engines (I think). As each cylinder fired, the sound pressure went up extremely fast at the start of the exhaust beat, suggesting huge exhaust valves, and the deep-throated roar was ... just ... beyond description. The only engine to come close was an extraordinary 1/3 scale model of a nine- cylinder radial aero-engine I saw years ago at a national model engineering exhibition. The crankshaft was anchored to the frame, and the entire engine and prop rotated around it. That's what you call air-cooling! Absolutely fantastic when he fired it up once an hour or so! > I live about 4 or 5 miles from a air force base here.

As you said - you had to be there. > Thanks for the link. My pleasure. I don't know when we'll get the Hurricane one - the man with the camera just put a two-word entry on Twitter this morning: "Hashtag HEADACHE" -- Regards Peter
