This remarkable and unique photograph shows a 'plane of the Royal Air Force actually in action in maintaining the blockade. Our bomber, far above the sea, had successfully attacked an enemy tanker carrying much needed supplies of oil to the enemy. Ablaze from stem to stern the tanker is sinking in the Channel off the French coast. The photograph was taken from another bomber of the same formation. Photo, P.N.A.
