The first one I saw was a double-cockpitted one. Flew like an angel.
I went again and again and was lucky enough to obtain a press-pass on the BoB anniversary in 2000. (Johnny Johnsson and Gunther Rall were there as special guests).
There were (out of memory) more than 20 Spitfires airborne at the same time. Then 4 Hurricanes, F4U's P47 F6F, just name'em!
What a blast. The Spitfires were however the only ones that showed some hair-raizing aerobatics. What one of the guys was doing was absolutely insane. (Perhaps he was a Frenchman

)
Anyway, I can mail you guys some pictures from this event and they are free to circle. "TheFox" has some of them I belive.
Duxford just rocks!!!!:aok
