In the dark, early days of the Second World War Britain stood alone against the terror of Hitler's all-conquering Third Reich. Our defence was in the hands of the men flying the Spitfires and Hurricanes of Royal Air Force Fighter Command. They were Churchill's Few. And, when the odds against success were at their most daunting, a handful of American pilots flew with them - in defiance of their own country's strict neutrality laws. There were fewer than ten of them - adventurers, farmhands, barnstormers, even an Olympic bobsleigh champion - who swapped the new world for the grass strips of East Anglian airfields. This is their story.
