Red Bull Flugtag 2015

Named after the German word for 'flying day', Red Bull Flugtag challenges the brave and brainy to design and build human-powered flying machines, then launch them off an 8.5m flight deck over water. The influence of 2014's world record-breaking flight is evident as a new generation of homemade flying machines takes to the skies - and 80,000 spectators experience some of the craziest teams yet.—Red Bull
