Ethan Swanson recently filmed himself as he jumped between two buildings in Chicago, Illinois (video below).
Swanson, who was wearing some sort of helmet cam, walked down an alley, grabbed some drainage pipe along the side of building and started climbing up, reports the Daily Mail.
Once he reached the roof of the building, Swanson looked over the edge, backed up, got a running start and jumped.
He tucked and untucked his legs in mid-air before the other rooftop is seen under his feet.
He crashed to the roof of the other building in a dive roll.
Swanson says he is in the process of training for American Ninja Warrior, a competition which pits competitors against each other using tests of speed, fitness and strength.
