"I'm relieved and delighted", said Stewart who passed both written and driving tests required to obtain a MSA competition licence at a rather damp Silverstone. "It's such a fast learning curve from the moment you first step into the car. At one point it was raining quite hard out there; I could hardly see out of the windows... and you really do need to be able to see out of the windows when you're driving fast!"
Despite the conditions the test was not about to defeat a man who has travelled around the universe at warp speeds. "I can't say it wasn't a challenge at times but I've enjoyed it very much", he reported. "I've watched too many professionals at work on the race track over the years to feel that I can now call myself a fully-fledged racing driver but it was exhilarating that's for sure and I'm looking forward to putting my new skills into practice."
Though new to Silverstone, the Captain's log does reveal that Stewart has a previous track record. "The only time that I've raced was on the Long Beach Grand Prix course in California which was in a Pro-Celebrity Toyota race and I really, really enjoyed it. But I've been in retirement for the last 10 years", he grinned before explaining why he was now making a comeback. "It was too irresistible... the chance to drive a great British sports car at Silverstone, what could be better?"
The final frontier for Stewart will come in a special, star-studded Celebrity Challenge race being staged as one of the highlights of this summer's Silverstone Classic powered by the AA (20-22 July), the world's biggest classic motor racing festival.
The Hollywood actor will line up on the starting grid alongside a host of personalities from showbiz, sport, TV and music all racing around the famous Silverstone Grand Prix circuit in lightweight, competition prepared Morgans capable of topping 130mph. Those taking part include award-winning chef Heston Blumenthal, lifestyle guru Jo Wood, "Comedy Dave" Vitty from Radio 1, Sky Sports presenter Vicky Gomersall, legendary rocker Brian Johnson from AC/DC and Strictly Come Dancing's Brendan Cole.
The Celebrity Challenge takes place on Saturday the 21st of July and will raise funds for the Birmingham Children's Hospital, the Bobby Moore Fund for Cancer Research UK and the RPJ Crohn's Foundation.
Adult tickets for 2012's Silverstone Classic powered by the AA (20th-22nd of July) cost from as little as £35 (plus booking fee) and special two- and three-day weekend tickets are also available with savings of more than 20 per cent if purchased in advance.
