Re: Cancer For All People on Earth

Whoa!
Karen you've got a lot to say.
Were engineers, we understand, but its a measured risk, a proportional response
to the conflict of exploration.
Nuclear fueled splace flight is presently inevitable but will eventually be
replaced by fuel cells.
That's the evolution of technology.
