	Over France and heading for the British Isles, using the clouds for cover. These He 111H-3s from Kampfgeschwader 55 have left their base at Dreux in France in the early morning. A good close look at this airplane will reveal the existence of added defensive firepower. Aside from the MG 15 machine guns in the belly gondola, dorsal position and the nose, this H-3 has an additional MG 15 on either side of the fuselage, sticking out of the rearmost waist window and an extra MG 15 poking out of the canopy just to the right of the pilot's position.
