I received this report from a close friend of Kirill who witnessed or heard most of the jump. Kirill has 500 skydives with 20 being with a wing suit, and 30 BASE jumps, with 2 being with a wing suit. This fatality began with an inadvertent low pull from a man who didn't do low pulls. His friend believes Kirill encountered a stability problem late in the flight. The friend, along with authorities, inspected Kirill's body and gear at the hospital. Kirill had opened his canopy, the slider is at the links. Both toggles are still stowed. The wing zippers are closed and the swoop cords are still over his fingers. The wing fabric between his legs is torn. His broken neck and one broken leg suggest opening and impact occurred at about the same time. The report intimates failure of the wingsuit material between Kirill's legs caused a stability problem at pull time. By the time Kirill stopped trying to overcome the situation and deploy, it is too late. Kirill is the first BASE jumper to die flying a wingsuit on a BASE jump.

Update 15th June 2019

• Cause Of Death: Impact sub terminal (near exit)
  It was not impact. He hooked ground when canopy was fully open.
  We heard sound of the opened parachute. Time was not enough for good
  fligtht but more than rock drop for that exit.

• "His broken neck and one broken leg suggest opening and impact
  occurred at about the same time."
  I guess he had a bad flight and unfortunately he opened his canopy low.
  After opening he hooked ground and broke leg. Leg's
  wing was torn in that time. Neck was broken when he fell.

• "The report intimates failure of the wingsuit material between

            Kirill's legs caused a stability problem at pull time."
             Suit was in perfect shape.
