Episode one introduces the new recruits. All are descendants of British, Australian, American and Canadian airmen, and while these new recruits struggle to come to terms with 1940s discipline and values. The new recurits are broken up into two flight crews testing themselves against the original training regime of the British Commonwealth Air Training Plan. Up at dawn, marching, saluting, cleaning, polishing, in classrooms and period planes, struggling to see whether they are the men their grandfathers once were.
