Flipping out over the Tower of London

July 14, 2009 Stuntman Robbie Maddison celebrated his 28th birthday (today) with yet another hard-to-believe stunt on Monday, using the Tower of London's lifting road bridge to perform a backflip over the Thames in the wee hours of the morning. Maddison has been regularly breaking his own world record for the longest motorcycle jump for several years and has currently pushed it to 106.98m (350.98 feet) as well as performing regular other outrageous feats as publicity stunts for Las Vegas casinos and sponsors Red Bull.
