I've looked at a number of possible destinations where you might have found a Comet & BEA - Luqa, Athens, Tel Aviv etc and various spots in Africa where they might have had the misfortune to have UK trucks but can't see it at all. The second truck on teh right looks vaguely French to me but I can't ID it so far
Quite a smart and distinctive tower but the rest of the place doesn't look like major airport even for those days.
looking at the pictures there is an absence of the "exotic" - plants, people, kit, roofs. Looks like jackets and shirts - so not extremely hot or cold
the shadows suggest the sun is very high in the sky so somewhere south of the UK I guess
