I can't speak authoritatively for Scott, but it is probably a typographical
error.  However, I do know that the "displacement" values for aircraft are
roughly equal to the volume of a rectangular box touching the wingtips, nose,
and tail.  So that "displacement" contains a lot of empty space.  A surface
ship, on the other hand, can get up to 13.5 tons of water displacement (minus
the amount needed for stability) per ton of standard (liquid hydrogen)
displacement.
