Actually in the state's, I think they aim this large ray gun type of device and shrink the doctor, staff and a (prior to ray blast) large space type of ship. The captain's job is very important. At least as important as the doctors. There are many dangers associated with a miniature space ship in the body. The least of which would be premature enlargement. Anyway I guess I am not sure if the can reuse the ship. But I'm pretty sure they can shoot bad things when they see them. I think since our ship can be refueled, washed, and used again that would make our process much more "green"
My apologizes, I couldn't help myself.
