Crew Meal
You give the impression that we had lots of LH 747's heading across the pond. There were, in fact, two or three taking Rover cars across for an exhibition when they were about to do a launch and there was not time to ship them by sea. The freighter[s] dropped in en-route.
On the topic of airfreight, we are frequently visited by An12's and the like bringing in car parts.
