One other problem that needs to be seriously looked at: EMP effects on the
vehicle & cargo during launch. I know rail guns have a strong enough
magnetic flux to be dangerous to people, let alone electronic equipment. A
launch system like this should have a much weaker field, but there might
still be a problem at high rates of acceleration.
