This thread has reminded me of being beaten up by a Puma sometime in the summer of '91 (possibly '92).
I was driving my new XR2, sunroof open, windows down and I think about 95mph (pushing 100) on the clock. I was on a section of road (probably the B390) a few miles past Stonehenge where a few feet to my right the farmers field drops away.
Pushing a 100 with the windows down in an XR2 generates a LOT of wind noise, with the stereo full on I am still not sure I could hear any music. Anyway given all that wind noise I still heard the rotors of the Puma and thought WTF is that. Glanced to by right to see a PUMA level with me!!! and maybe 2 rotor disc away.
This did ring a bell somewhat and I was going to apologise. But then you said the farmer's field dropped away and that the aircraft was level with you. I'd have been below you so it wasn't me...
