2. The fuel is provided the own atmosphere
If there is no motor, well kerosene neither. The gliders don’t use any type of fossil fuel, which makes it just perfect when we live in a era where everyone is looking to respect the environment. The glider not only is nourished by the currents and thermals that are born from the atmospheric changes, establishing this, we review all the technical aspects. But, what is needed is just a small push to take-off. In occasions, a windlass is used but, in the majority of times, a light aircraft puts in front to drag the glider just like a road crane.
