Extreme athletes have been using wingsuits — unique jumpsuits with fabric stitched between the arms and body and between the legs — to fly untethered for many years. However, while the "birdman" or "squirrel" suits allow daredevils to soar in the skies, the pull of gravity makes it impossible to accelerate or fly higher. To push past the limitations, Austrian stuntman Peter Salzmann teamed up with German car manufacturer BMW. The result is an electrified wingsuit, which allows flyers to zoom to higher altitudes at speeds of up to 186 miles per hour!
