GHOSTS IN THE ROYAL SERVICE
In the beginning 1960-ies to the leadership of the British Navy faced the problem of replacement fighter aircraft “sea vixen” (Sea Vixen) more modern machine. First, the sailors wanted to buy from your company “Hawker Siddle” (Hawker Siddeley) supersonic aircraft vertical takeoff R. 1154. But because of its high cost and the inevitability of problems in development, they turned their attention to the American Phantom, which was relatively cheaper and did not require a large investment of time to create.
THE SNOWMOBILE RIDE YOURSELF!
When winter comes and the snow is “fluffy blanket” covers the ground in many areas, the only vehicle able to overcome it “fluffy blanket”, it becomes tracked all-terrain vehicle or, more commonly, a tractor with a sled-scraper. Of course, you can buy a Japanese ski-goose-nicou Yamaha (though it is worth more than another car) or buy now rare a cheap domestic “Buran”. However, always need such a powerful machine?
WITH THE WING… ON SKIS
Sail is one of the oldest inventions of mankind, who played a revolutionary role in the development of navigation. The Millennium operation has made sailing propulsion is very perfect, and it seemed that his aerodynamic abilities reached its practical and theoretical limit. A new stage of development of this propulsion system uses the wind power, was the creation of a rigid sail with double-sided sheathing.

CORD CLASS F2B
Beginners only pilots first, as a rule, “fly” for simple models, is designed for small “cubic capacity” of the engine. They learn to manage to work out a complex aerobatic figures. Over time, performance of simple models no longer satisfy them. There is a desire to build a more serious and heavier the aircraft under the engine more “cubing”. And this is not surprising because in such a model, the flight characteristics much better.
