I've cleaned up, repacked the UV-s and added a subtle AO pass to the texture. It's in need of a full retexture though.
I rescaled it too, so the window size is more meaningful. It's about 50m long now.
Also adjusted the stats, so it has capacities according to volume. Thrust is very low, deltaV is relatively high, about 17.000km/s fully laden, and you can churn out around 75.000km/s if you load it up with water.
Pleasegive it a spin to see if there's any problem with it.
