Pics of the Cranfield visitor G-BUYF in 1994: Registered as a Harris RW Falcon XP ex N512AA... American Aerolights was the plans or kit supplier. I flew in to the PFA that year and didn't stay more than two or three hours which was a rush
but memory says it may have been there with its US reg a year or two earlier.
