Does anyone know why the Seaview was massively redesigned between seasons 1 & 2? The modifications to the sets and model give the impression that the sub is actually much smaller than it was during season 1. The Seaview actually seems to lose a deck when they changed the number of windows from 8 to 4. (not to mention the fact that merging the nose with the control room seriously screwed up the ship's internal arangement).
