This was his first time on this jump and his first jump of the day. He was current and not nervous about the new jump. Condition both at the exit point and in the valley were perfect.
Boris jumped and had a stable exit, he dove aggressively in order to fly over terrain at the bottom of the cliff. After diving for a few seconds, he flared in order to match the angle of terrain, but failed to achieve level flight in time to avoid collision. He impacted the ground in full flight position and he was killed instantly.
