A thing I noticed about your Class L heavy shuttle...
Doesn't appear to hold many people, is that right?
I know it's not your original design and that you scaled it to be of comparable size to TOS shuttles.
But eliminate the "nose", as that doesn't appear to be habitable cabin space. Then the "hatchback" aft end doesn't appear to hold enough headroom for more cabin space.
That only leaves the very middle of the craft for the cabin. If the side hatch is any indication of size, it appears the Class L can only hold about four persons.
I'm just saying, guess it doesn't make a difference.
I very much like the heavy Class L shuttle design, Gremlin-esque as it is. Your additional work on it is also fairly impressive. Well done.
