It can't go into Earth orbit without a course correction, since if it were in an orbit it would return to the last point delta-V was nonzero, which corresponds to the catapult. It will likely have left due to Earth's rotation, but that's still deep in atmosphere. So, we come up with the following questions: What's the terminal velocity of an unladen cow? Will the cow burn up in re-entry? Or will there be parts only medium well? Is this an African or a European cow? If it burns up on re-entry, wouldn't it also burn up on leaving the catapult? What does any of this have to do with comp.lang.c? David Thornley (So how about *solar* orbit?)
