Mr. Fly isn't part of the mass of the vehicle if he's ballistic, until he hits a
bulkhead. Of course, if there's vaccuum in the cockpit, that might be rather
soon. And if we're accelerating the ship too, even sooner. 

Yuk. 

Hey, ya know what's the last thing to go through a fly's mind when he hits the
