Hummel Bird

Hummel Bird began as a modified Watson Windwagon, but the designer/builder, Morry Hummel, of Bryan, Ohio, highly modified it and called it Hummel Bird, using the Revmaster R-800 rather than the half-VW. The LSA airframe has been modified and strengthened, tail area increased, and a locking tailwheel added for better ground control. A high L/D Schreder #3 airfoil and flaps also were used.

Excellent single place aircraft. Features all aluminum construction. Fast and inexpensive to build, many were flying.

Humber Roger Sommer biplane

The fifth aircraft produced by Humber was a British version of a biplane designed by Frenchman Roger Sommer, and derived essentially from the Farman III of 1909.

Two Roger Sommer biplanes were completed towards the end of 1910. One of the latter carried the first official air mail in India. This event was part of the Universal Postal Exhibition held in Allahabad in India during February 1911. During the exposition, the French pilot Henri Pecquet, on February 18, flew across the Jumna river from Allahabad to Naini Junction, in all some 8km / 5 mi with 6500 letters. Four days later, a ‘regular’ service for the duration of the exhibition was opened by Pecquet and Captain Walter G Windham, the aircraft that they used again being the Humber-Sommer biplane.
