Wheelock/ > arpanet: crash!bnw@ucsd > uucp: {ihnp4, cbosgd, sdcsvax, noscvax}!crash!bnw When you mention "...the problem of mounting a machine gun on a jet that flies faster than the muzzle velocity of the gun" are you alluding to the phenomenon of the expelled projectile loosing velocity after leaving the muzzle? This is actually a result of atmospheric drag causing the projectile to loose energy. As we learned at Pensacola, FL "...after firing a short burst...pull up!" You also mention that "The universe has rules, and you can't break the rules by going faster". This assumes that we know all the rules. Regards, Richard ------
