I plopped a Droonaunt onto his rover and successfully flew him to Mars. The craft crashed while landing but to my surprise the rover was ejected (along with the stowaway) and started rolling down a hill. Unbelievably, the only damage was to the rover's drill. It was torn off during it's tumbling.

Ive always thought more along the lines of a "dune buggy" (get it?) :D
You know.. cuz of the dunes on Mars/Cylero... Get going fast enough, hit a nice-size dune and watch it FLY. ;)
Use it on the moon/Luna and it's hard to keep from tumbling in the sky...
