May 1940. Britain is losing the war. Churchill is desperate for bombers. Aircraft deliveries from U.S. factories are being ravaged by German U-Boats at sea. Can the planes be flown across the storm-swept North Atlantic to Britain? A ragtag band of determined civilian flyers comes together to deliver planes by the thousands. At the time, transatlantic flight was in its infancy, and knowledgeable observers believed such a scheme to be impossible. Yet the plan was a success, and by the end of the war, 9,027 aircraft were delivered across the Atlantic, helping to turn the tide of the war. The documentary tracks down some of the surviving flyers and their planes.
