Does anyone know if there was any thought or discussion regarding the possibility of trying to show other ship classes such as in "The Ultimate Computer," "The Omega Glory" and "The Tholian Web?" We know they went with reuse of stock footage because of time and budgetary constraints, but was a possible alternative even considered even if just momentarily? After all even though they managed to whip up a quick model for the Constellation
it was always meant to be a ship similar to the Enterprise.
But what of the others?
