[Not-A-Normal-Robot]

NFA has Advanced Propeller Engines. They consume EC and IntakeAtm (basically, generalized IntakeAir that doesn't depend on an oxygenated atmosphere).

This mod thinks IntakeAtm is a regular fuel and therefore doesn't account that IntakeAtm is basically infinite when you're in a planet that has atmosphere.
This is a problem since when your rover/ship is mainly powered by these propeller engines, you can't really use Bon Voyage without it just stopping after 2 seconds.

Fixing this should be easy:

• Adjust speed based on atmospheric pressure at the vessel's current altitude if it uses engines that consume IntakeAtm.
• If celestial body has no atmosphere, then show a message that basically says "Rover/Ship stopped: no atmosphere"
