And this is why people don't like me...
Mass tons (metric tons, I think we codified spelling that as "tonnes"?)
vs. displacement tons, which is volume, 14 cubic meters per dton, 14 cubic
meters of LHyd masses 1 tonne.
So to get Trav "starship tonnage" (displacement) for Shuttle and B-777
you'd need to know the volume of those things, which is harder to find
than you might think, as most published volume figures would be "internal
cabin volume," where Traveller displacement tons volume is actually
Archimedes39; "Eureka!" crown in a bathtub volume: how much physical space
does it take up?
And then even if you got that figure for the 777, Traveller spent years
trying to come up with a rule on how much hangar volume is required per
dton of carried craft. It started out carrying craft at tonnage, which is
wrong, and I think values after that were like 1.4x, 2x, 5x, and so on,
which not only make it hard to carry craft, but still understate it. I you
were to try to carry a fully assembled 777 sitting on its landing gear it
would probably store at something like 50x or more.
