seems you are weak in science. By weightlessness I didn't mean the object's weight. I meant the weight of the person travelling in it. Do your homework in physics:P. You are telling about Classifications. But what are they called Ships in general. So your argument is weak. The term is not just fighter. the term is fighter class ships NOT PLANES. So put up a valid argument pls... And its not BOATS its SHIPs:)
