Pilots have reported that German anti-aircraft fire is extremely accurate. Nevertheless, very few aircraft have been destroyed by this means in western Germany. On 8th September French reconnaissance aircraft was brought down at the height of 16,000 feet, and on 11th September a similar type of aircraft was destroyed by ground machine gun fire. Four other aircraft were missing during September and may have been shot down from the ground. It is more probable however that they were lost by fighter action.
