Тут написанно, что

August 1912, Lieutenant Wilfred Parke RN became the first aviator to recover from an accidental spin when his Avro biplane entered a spin at 700 feet AGL in the traffic pattern at Larkhill. 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, and horrified observers braced themselves for a fatal crash.
Штопор был непреднамеренный и случайный

Первый задокументированный преднамеренный ввод и вывод:

The first documented case of an intentional spin and recovery is that of Squadron Leader J.C. Brooke. In the summer of 1915, Brooke recovered from an accidental spin, and was urged by his students to repeat the exploit. He agreed, and found that he could easily recover from a spin using Parke's technique.
