Great seeing the pics of the Vanguard and the Britannia. I remember having to learn some "Technical German" as well as German, and one important term was "Unterboden besdlastungsgewicht" . (under floor bearing weight) It would have been useful to the loader of a Trans Meridian CL44 at MAN in the late 1960's. A voice saying "You'd better go over to the CL44, and see the damage" A ICL computer had been loaded with a large fork lift truck into the swing tail a/c. The cargo had completely gone through the floor, into the lower fuselage.
Of course it was a time of computers being the size of a garden shed.
