Interestingly, I'd call Burt the end-century Bleriot. Think about it, Bleriot was working in the days when there were no real rules governing what an aircraft looked like, so he had to make it up, and the Bleriot XI was the shining (for the period) result. Meanwhile Burt was in a similar world, oh aircraft were common, but no-one had any idea what a circumnavigation-capable aircraft or private space plane were supposed to look like, and so he had to guess and experiment and invent stuff too, and the Voyager and SpaceShipOne turned out to be similar successes to the Bleriot XI.
