If circumstances require it, reverse thrust can be used all the way to a stop, or even to provide thrust to push the aircraft backward, though aircraft tugs or towbars are more commonly used for that purpose. When reverse thrust is used to push an aircraft back from the gate, the maneuver is called a powerback. Some manufacturers warn against ...
Jean Bertin was an early advocate of the hovercraft, and had built a series of multi-skirt transport vehicles for the French army known as the "Terraplane" in the early 1960s. In 1963, he showed a model of a vehicle similar to the early Hovercraft Development concepts to SNCF .

However after a bad flying experience he gave up personally piloting himself in 1974. [2]
Rotated wingtip Rotated wingtip (from below and behind). The Short SB.4 Sherpa was an experimental aircraft, featuring an unusual aero-isoclinic wing. [6] This radical wing configuration was designed to maintain a constant angle of incidence regardless of flexing, by placing the torsion box well back in the wing so that the air loads, acting in the region of the quarter-chord line, have a ...
