There was something about this on the Key Publishing forums recently (in fact, might still be on-going)
The four UK-based two-seaters are:
MJ627 - M & P Bayliss, flown by Paul Day, East Kirkby, Lincs
ML407 - Carolyn Grace, Dufxord,
PT462 - Anthony Hodgson, Wales
PV202/IAC 161 - ARCo, Duxford (under rebuild)
US-based two-seaters:
MT818 (prototype MkVIII two-seater) - Jack Erickson, Oregon (I think)
MJ772 - Seattle Museum of Flight (again, I think) airworthy and with rear cockpit faired over
TE308 - Bill Greenwood, Colorado
astir8 - know what you mean! Get in close, hammer the ******s then get out, quick!
Gun-cam footage was very haunting in my opinion - especially stuff like that.
