Of course, the Biffo that was here in '86 took part in the "50 years of Heathrow" parade down the approach to 27R in 1996, shortly before its prang at Enstone. From memory, it went something like a Rapide or two, the "Frightener", Dove, Heron, DC-3, etc... finishing up with an MD-11.
Merlin, must try and arrange a beer sometime in Feb.
