The Red Bull Air Race, started in 2003, is a series of air races, held all over the world, where pilots fly specialized aerobatic planes (with top speeds of over 250 mph / 400 kph) through a series of gates, racing the clock, accumulating points toward the championship title. Pilots must also perform specific manoeuvres while passing through the gates. The photos below are from the most recent two races, in Budapest, Hungary, and Porto, Portugal. The final race in the series is scheduled for November 1st, in Perth, Australia, and video of the event will also be streamed over the web. (17 photos total)
