Back around 1980, I went up to Blackbushe with some friends to see an Invader that had arrived recently, IIRC. Having seen the Invader we wanted to get up around the hangars to see of there was anything of interest visible.
Cycling along parallel to the runway, we heard a howl from behind us. We stopped and looked around as a beautiful gold and white Mustang beat up the runway. As it climbed out again, we could hear something coming in behind it and sure enough it was followed by a Thunderbolt.
ISTR that the Thunderbolt was N47DE and the Mustang became G-PSID
