This is a tribute to the heroines of the Second World War, the women pilots who ferried planes to the front line or flew air ambulances as members of the British Air Transport Auxiliary or as American Women’s Airforce Service Pilots (WASPs); in Russia, women fought as combat pilots.

The Luftwaffe, too, had its women pilots. They tended to be treated with scepticism by male colleagues, who sometimes openly questioned women’s physical and intellectual fitness to fly. But the women earned respect - from their enemies as well as their own side. As well as archive footage of air battles and extracts from newsreels, there are interviews with survivors about this forgotten piece of history.
