Every airplane is designed to perform a particular mission.
Some are good at carrying cargo, some at crop-dusting, some at comfortable passenger transportation. Air superiority fighters are optimized for speed and maneuverability. It has the speed, firepower and maneuverability to make it the king of the hill. If a flight happened to be the very first flight on a new aircraft, that added a little extra thrill to the process. If any first flight on an F-14 can be said to be perfect, this was it.
