I'm with SSD in remembering the Caravelle's appearances at Ringway. When I stalked the terraces in the '70's they were frequent enough but stood out from other types both on the ground and airborne. The AF evening arrival was usually a Caravelle along with regular Sunday appearances by Sterling. The holiday charters accounted for the bulk of appearances with Aviaco being the front runner along with JAT. Infrequent visits uncluded Transavia and Transeuropa, the French Air Charter International and an Italian outfit that used to stand in for Alitalia, (SAM I think). I'm not sure if Spantax and Balair used to operate Caravelles into Ringway as well. The only chutes I saw streamed were AF's.
