the wright brother invented the glider in the 1890s it was a successful one similar to a airplane but without the engine
The first glider was invented in 1891.
If the glider has a roasing chicken inside, it will cause some convection waves, this will lift the Glider up.
Yes, gliders have an airfoil very similar to that of a powered airplane. Gliders do generally have a wider wingspan in order to handle better at low-airspeed & therefore take better advantage of thermals or ridge-lift.
