National Red Bull Flugtag

Taking off in Washington, D.C. and landing in Long Beach, Calif., with layovers in Miami, Chicago and Dallas/Fort Worth, National Red Bull Flugtag, the homemade flying craft competition, made history today by taking place in five cities in one day. Adding to the already-extraordinary day, the The Chicken Whisperers, a team of aerospace and mechanical engineers from Palo Alto, Calif., proved that chickens can indeed fly, soaring a staggering 258 feet and shattering the old world record, set in Germany in 2012, by 29 feet.
