TheStressPuppy made a bunch of shuttle models for his TOS Homeworld mod; somehow I got a wild hair to drop them into SFC2 and see what happened... well, this is what happened:
The classic Galileo 7:
A "recon" variation of the Galileo:
The TAS Copernicus:
The TAS "Heavy Shuttle":
And Stress's version of the "TOS Type 9" shuttle, originally designed by Nick Porcino/Meshula Labs:
The pictures are small because I was experimenting with having them at their "true scales," between 7 and 12 meters; the stock shuttle is about 20.
