I visited airshows at Duxford and Old Warden (England) in 1998. I'm more interested in WW1 and WW2 airplanes and they were the kinds that flew during that flightshow (though I reckon the WW1 planes were no originals). It was quite impressive. Among other they had the F4U Corsair, a P51-D Mustang , a Spitfire (Mk IX I think), a Hurricane, a B25 Mitchel, and a Me 109 (which looked kind of strange as a different kind of engine required the nose to be shaped differently). I got to know a couple of WW2 pilots (not there, but on different occassions).
