Ahh my reply to your quote above was an unfinished draft of a reply I started typing this morning and then abandoned.And I'm forgetting my Trek history; the only reason they were able to afford to build the interior and exterior of the TOS shuttlecraft was because AMT did it in exchange for being allowed to make plastic model kits of the various Trek ships.

I was just gonna say that I doubt that the series would’ve gotten enough money to build a new full sized shuttle from scratch, but fortune would have it the bigger budgeted STV required a couple for its story, and TNG got to reap the rewards.
