Makes the Spark hangar fully vacuum, so it can use its sensors while docked again like it used to.
Swaps the fuel line around so the fuel connector pumps into the fuel tank, rather than into the thrusters directly.
Airlock to distro merger valve starts disabled and the shuttle begins with an airlock air canister. Distro is very high pressure, so the airlock always relying on it made cycling very slow. Should cycle faster now. Air canister in the hangar has been replaced with a PAP.
Spark airlock now cycles air-to-air by fully emptying foreign gas on an inward cycle, and then refilling with air from the canister. Landing on planets with toxic atmospheres shouldn't flood the shuttle with their atmospheres, or contaminate the airlock canister.
Windoors on front of the Spark cargo bay have been removed so the out vent works properly.
Spark airlock has catwalks to match the Intrepid.
Replaced the odd half-walls at the back of the cargo bay of the Spark with full walls pulled from the front of the spark.
