The world's first becoming airborne in a heavier-than-air powered aircraft was not the Wright Brothers in December 1903 but probably New Zealander Richard Pearse some 8 or 9 months earlier. With further development the Wrights did then go to sustained, fully controlled flight in 1904/5. Come see how Pearse did it. Hope you enjoy. Cheers.
