Don't let the title put you off. This is in fact Ewan McGregor and his brother flying bombers. Why, that's not hot (or trivialising the war) at all. Here the actor and his sibling, Colin (an RAF pilot), retell the story of the 1940 air battle that proved to be a turning point in the Second World War. The pair get hands-on experience of flying period fighter aircraft across the skies of England, giving Colin an opportunity to contrast his training in modern combat techniques with the skills required to master the Spitfire's less sophisticated technology, and meet those who participated in the conflict itself. As part of the BBC's Battle Of Britain season, they discover how a handful of determined young RAF pilots saved Britain from invasion by the most powerful war machine in the world – the Nazi Luftwaffe.
