If 400' @100mph becomes the hard and fast standard it will kill any competition in this country and abroad. But hey, America isn't competitive at anything anymore other coming up with new and inane rules to regulate everything for our safety and security. The Japanese whom we dropped bombs on in WWII kcik our butts at everything, education, technology, education even baseball. What's one more thing that most Americans will never really miss? We just play with toy airplanes anyway. Isn't that right?
