Are hovercraft controlled with Driving or Piloting? Plus other vehicle skill stuff...

[Lord Azagthoth]

I always tell my players that with piloting you can control the height of your vehicle yourself while with driving you are ground bound. A hovercraft is also ground bound. Just have to figure out what type of controls a particular hovercraft uses to get the defaults right.

As for halftracks, some used tank controls (US halftracks early WWII). Later they adapted this when they captured a German halftrack, which used a steering wheel).
