Maupin-Lanteri Black Diamond

The Maupin-Lanteri Black Diamond represents a significant, segment of early American aeronautical activity: the dozens of lone amateur enthusiasts who successfully built and flew aircraft of their own design using hardware store supplies and dogged determination. L.B. Maupin and Bernard Lanteri patterned their airplane after the successful early Curtiss pusher biplanes, with front and rear horizontal control surfaces and a tricycle landing gear. Yet, many of the details were of Maupin and Lanteri's own design. They built a very successful aircraft with little guidance and, in the hands of pilot Weldon B. Cooke, it made numerous significant flights and won several important flying prizes in 1911 and 1912.

Although some secondary accounts suggest that the Black Diamond flew in 1910, a series of newspaper articles chronicling its construction appeared between March 4 and September 23, 1911, that indicate it was built during the first half of 1911 and first flown in June of that year.
