This machine is a biplane of the Bleriot type, except that it has sliding planes at the wing tip for securing lateral stability. This machine has been making small jumps for a couple of weeks. It is equipped with a Ford automobile engine of 22 1/2 h.p., four-cylinder, water-cooled. The power plant weighs 200 pounds, and the whole machine 700 pounds, including the aviator. Warren S. Eaton was driving the machine when it went over on to its nose. It was running on the ground at the rate of 25 miles per hour when the front axle broke. As the tail was high in the air at the time, the tips of the skids stuck in the ground, and it ended up as shown. Mr. Eaton was thrown into the framework, but escaped unhurt.

The 1913 streamlined “Dolphin” was a tractor monoplane with plywood-covered fuselage, powered by 7-cylinder 80 hp rotary Kalep engine. Both machine and motor were built at the “Motor” company in Riga, today capital of Latvia. It was designed by Russian military pilot Viktor Vladimirovich Dybovskiy, with help of his brother Vyacheslav.

Young military officer Georgiy Antonovich Dyakov, from Kutaisi (Georgia) built this aircraft of his own design in 1912. It had strong and extremely simple construction. The pilot was seated on on the bicycle seat. He used a motorcycle engine of 7.5 HP. Tests showed that aircraft was unable to take off.
