Ueli was jumping an L shaped building, the 88m tall Sunrise Tower, during a promotional event. He jumped the side of the building facing the bottom of the L handheld. The glidepath he was on would put him very close to the edge of the building. He tucks his legs up and tries to clear it but it proves too be not enough and he clips the building edge with his legs. The impact flips him up and unloads the canopy. When his weight reloads on the canopy it appears to be asymmetrical and Ueli turned into the ground. He was taken to the hospital and treated in the Intensive Care Unit for two days at which point he died.

Ueli was a very skilled jumper and respected by the community.
