Great Site !!
I can tell you that the Bristol Freighters at Lydd were loaded by the airline crew!.
You arrived at Lydd and parked in the car park. Then you waited in a lounge that viewed the apron and watched them load your car. Then they loaded passengers in the upper deck and the procedure was repeated in Le Touquet !
Came to Luton in 61 with Autair’s only aircraft a DC3 G-AJIC
Lived in the flying club and rate included full Engish cooked by Ma Battle complete with headscarf and Cigarette !!
Autair had the contract to maintain and operate the King of Libya’s royal flight in Benghazi with 2 Lear Jets.
I ran the maintenance side there and the Bristol Freighter trip was when I bought a new Ford Cortina Estate and drove from Luton to Behghazi !!
