It promised to be spectacular and it has lived up to the billing. The Buddh International Circuit, India ’s first Formula One circuit, was unveiled to the world on Tuesday -- just 12 days before the inaugural Airtel Indian Grand Prix on October 30 -- beaming in the mellow October sun. Jaypee Sports International Ltd has pumped in $400 Million (Rs 2000 Crore) in the construction of the track, which showed in its world-class look and finish. Over 5,000 workers and 300 engineers and officers have worked round-the-clock to get the track –spread over 350 hectares – ready in time. While F1 might be a new concept for India , people are getting ready to grab the opportunity to watch 24 of the world’s best drivers in the country.
