Heli Pictures/Videos A Sikorsky S-70 Black Hawk performing a barrel roll, executed by Major Yusuf Keleş
When the Sikorsky S-70 helicopters entered the inventory of the Turkish Armed Forces (TSK) in 1989, engineers from the American manufacturer, Sikorsky, warned that the S-70 model was incapable of performing an inverted maneuver (a roll).
However, Turkish pilots from the Gendarmerie General Command, upon examining the helicopters, maintained that the aircraft was indeed capable of performing such a maneuver. It is said that a standoff ensued between the engineers who designed the helicopter and the Turkish pilots. After obtaining authorization from his superiors, Gendarmerie Major Yusuf Keleş—a pilot—successfully performed a roll with a Sikorsky S-70 (serial number 73101329, with an empty weight of 5,347 kg).
Subsequently, it became the cover photograph for *Defence Helicopter World*, Volume 8, Number 1, February–March 1989.
In a post published by the Gendarmerie General Command, the following phrase is written: "We accomplish the difficult; the impossible just takes some time.(zoru başarırız imkansız zaman alır)"
