Airplane gliding occurs when all the engines of an aircraft shut down, but the wings are still functional and can be used for a controlled descent. This is a very rare condition in multi-engine airliners, [1] though it is the obvious result when a single-engine airplane experiences engine failure.
The list of aircraft accidents and incidents caused by structural failures summarizes notable accidents and incidents such as the 1933 United Airlines Chesterton Crash due to a bombing and a 1964 B-52 test that landed after the vertical stabilizer broke off. Loss of structural integrity during flight can be caused by:

Another way of putting it, the airplane swaps ends. This is a ground loop." [4] The Schleicher ASK 23 is a single-seat glider suitable for new pilots. It has a nose-wheel, and its main wheel is behind the centre of gravity. This avoids the risk of ground-looping at commencement of takeoff in a crosswind behind a tow plane.
The airplane is designed to be able to withstand a bird impact. However, sometimes the circumstance is more than what the engine is designed to ingest, or it causes some particular damage.
Maximum emergency braking was applied and retained, and the plane came to a stop after a landing run that consumed 7,600 ft (2,300 m) of the 10,000-foot (3,000 m) runway. Because the antiskid and brake modulation systems were inoperative, [ a ] the eight main wheels locked up, the tires abraded and fully deflated within 450 ft (140 m), and the ...
The 360° Power-off approach requires the plane to glide in a circular pattern, starting 2,000 ft or more, above the intended landing point. [5] When the aircraft is positioned over the landing point, the throttle is closed and again, the proper glide speed must be attained.
As with sustained flight, gliding generally requires the application of an airfoil, such as the wings on aircraft or birds, or the gliding membrane of a gliding possum. However, gliding can be achieved with a flat ( uncambered ) wing, as with a simple paper plane , [ 2 ] or even with card-throwing .
