As the most famous Iowan ever in space exploration, Kirk drew fame as perhaps the best soldier/statesman/explorer of Starfleet's first hundred years. Although questionable at times in his interpretation of the Prime Directive of non-interference, his charm, leadership and impromptu creativity combined to complete many a mission against the odds; in fact, his starship Enterprise is the only vessel Starfleet honors with its original registry number on each succeeding namesake. It was during these early voyages that he would also come to acquire the tag of being a sometimes rogue in the chain of command, although his acts always aimed at a higher purpose, and they displayed why at the time he became the youngest starship captain in history.
