Yes DC-9-32, those Altair Caravelles but not forgetting their DC-8s. Talking of DC-8s- Air Spain in those wonderful colours. What about Channel Airways Golden Viscounts and Invicta Vanguards doing MoD flights to Dusseldorf and Lourdes Pilgrim flights. Plus Sterling Caravelles in their droves at Luton in the 1970s.
Going back even further Spantax DC-7s and SAM DC-6s at Gatwick with the Wardair B727 coming all the way from Canada!
