He didn't build the Phoenix, Lilly and other technicians did. He designed the engine and was supposed to fly with Lilly (the real pilot too) up there.
Remember how Riker and LaForge (an enginner) were up there with him? It was because he knew how to operate the engine and when it was ready to be used, but nothing else. LaForge and Riker di the rest of the piloting and stuff.
Kirk's line is twisted by history and such, like how they forgot he was a drunk. Like how Spock says the Romulan War was fought with "Atomic" (not nuclear) weapons, when that makes no sense.
