Businessman Steve Hartley has dedicated his fortune to a quest for speed. He already owns a McLaren Formula 1 car and two helicopters. But his latest project leaves both standing.? His L39 jet is a Cold War-era plane rescued from the corner of a hangar in the Baltic States.

At St Athan in Wales, engineer John Sparks and his team of ex-Navy and RAF? engineers begin the task of reassembling the Czech-built jet from nine parts delivered by lorry.

The first engine run goes well... then the team hit a major hurdle.? An ejection seat is found to be unusable and Steve must launch a worldwide search for a replacement. In a real-life story with some of the ingredients of a thriller, his quest comes up with an unusual solution...buying another jet.? But will his first plane ever take to the air?
