Ukraine's United24 news service released the footage on October 19, describing the operation as a historic first carried out by soldiers from the 92nd Assault Brigade and the 30th Mechanized Brigade.
The wounded soldier was reported to be stuck in a minefield and at risk from Russian kamikaze drones. Media reports suggested he was as far as 18km behind enemy lines, though the rescue distance was later given as 8km. With a land rescue impossible, Kostya clipped himself into a harness attached to a heavy Gurzuf Defence hexacopter. "That's it, we can take off," he said once strapped in.
The drone is rated to carry up to 130kg and has previously moved loads of 90kg over distances of up to 25km. Kostya weighs about 80kg. The flight was supported by a fleet of Ukrainian drones, including kamikaze devices and UAVs fitted with anti-drone nets.
UAV operator 'Black', from the 20th Mechanized Battalion, said the team stayed in contact with the soldier throughout. "We were constantly in touch with him," he said. "A lot of people were involved, and everything worked out for us."
On touchdown, the control room told Kostya: "Congratulations, you're on the ground." The soldier is now receiving treatment and recovering.
A brigade leader, callsign 'Napalm', said the operation could mark the beginning of a new system for evacuating wounded or stranded soldiers using drone technology.
