It's been called the Formula 1 of the skies, and although new, it's fast becoming competition for the most popular motor sport - so what am I talking about? Well, it's the Red Bull Air Race! Conceived in the US by Red Bull, it was first maybe dismissed as a marketing stunt when the first race was held in 2003, but it became immediately clear that the idea was a winner.
Races followed in several countries, leading to the first Air Race World Series in 2005.
Unlike the baseball world series, this one actually takes place around the world, with competitors from around the world! The event was bigger in 2006, and bigger again this year, with the 10 race season taking 7 months.
You can see why it's called the Formula 1 of the skies, both for the money making potential and the spectacle, which came to London for the first time in July 2007.
A venue hosting the event gets to show spectacular landmark shots to advertise itself, and the crowd gets to see motor sport which is probably more exciting than F1.
With the small lightweight planes getting up to around 400kph, and the pilots facing up to 9G forces, it's no mean feat as they execute tight twists, turns and loops around a timed course of gates.
If a driver crashes in Formula 1 nowadays, they are so cushioned in the chances of survival are enormous, but a crash in one of these planes would mean big problems.
Not that people watch to see crashes, but it's the element of danger.
Naturally there are only a few pilots in the world who can pull off the moves required, but as the sport continues to grow, you can be sure that even now there are stunt pilots of the future chomping at the bit to have a go.
What a superb new event this is! Brilliantly conceived, excellently marketed, it starts to make the overly technical, in-fighting Formula 1 seem like a real bore!
