Air racing is a new flying discipline with skilled pilots compete against eachother on speed and precision as they fly around a range of obstacles that form an assault course in the sky.
The very first Red Bull Air Race took place at AirPower in Zeltweg, Austria in 2003 and was hailed as a great success.
It was clear that there was a huge potential for the competition. Subsequent air races were then held in Hungary, England and the USA and since then it has evolved into its current format, the Red Bull Air Race World Series.
