If an aircraft has not been certified for spin recovery, it should be assumed that spins are not recoverable and are unsafe in that aircraft. Important safety equipment, such as stall/spin recovery parachutes, which generally are not installed on production aircraft, are used during testing and certification of aircraft for spins and spin recovery.
It has been used as a trainer aircraft by several armed forces, as well as civilian operators. In the mid-1990s, the aircraft became controversial in the United States after three fatal accidents during US Air Force training operations. The Firefly has poor spin recovery, and has been involved in at least 36 fatal accidents. [2]
The Fulton system in use The Fulton system in use from below. The Fulton surface-to-air recovery system (STARS), also known as Skyhook, is a system used by the Central Intelligence Agency (CIA), United States Air Force, and United States Navy for retrieving individuals on the ground using aircraft such as the MC-130E Combat Talon I and B-17 Flying Fortress.

He therefore applied up elevator and possibly applied the wing warping control, and at once the aircraft entered a spin. Parke attempted to recover from the spin by increasing engine speed, pulling back on the stick, and turning into the spin, with no effect. The aircraft descended 450 feet (140 m), and observers braced themselves for a fatal ...
The 1991 RAAF Boeing 707 crash occurred on 29 October 1991, resulting in the loss of the aircraft and all five crew members. The aircraft, serial number A20-103 with the callsign Windsor 380, was on a training flight involving a demonstration of the aircraft's handling characteristics at minimum control speeds in a "double asymmetic" condition, with two of its four engines at idle power.
In 1915 he joined the staff of the Royal Aircraft Factory at Farnborough. He developed a mathematical theory of aircraft spin recovery and later learned to fly so that he could test his ideas himself. [11] Prior to Lindemann's work, a spinning aircraft was almost invariably irrecoverable and the result to the pilot fatal.
The Sikorsky MH-60/HH-60 Pave Hawk is a four-blade, twin-engine, medium-lift utility military helicopter manufactured by Sikorsky Aircraft.The HH-60 Pave Hawk and its successor the HH-60W Jolly Green II are combat rescue helicopters, though in practice they often serve humanitarian and peacetime disaster rescue.
