Publisher's Synopsis
This book tells the experiences of three very talented parachutist brothers, inventors and engineers, named Nikolay, Vladimir and Anatoly Doronin.
Their creative character made a great contribution to the development of parachuting and skydiving in the USSR and increased the safety of parachute drops from airplanes, earning the gratitude and respect from pilots and parachutists thanks to their inventions' reliability.
They were part of the VDV (Soviet Union Airborne Forces) for a large part of their lives, and despite their youth, they invented the PPD-1, the world's first automatic activation device (AAD) designed to open a parachute, housed inside a small grey box, causing a revolution in the world of skydiving.
