From: Scott Richardson's Thesis "A History of Eighth Air Force Fighter Operations 1942 to 1945"
-------------------------------------------------------------------------------------------
Strafing airfields was particularly dangerous due to the numerous antiaircraft guns. German flak-towers lined the fields and were usually the first guns attacked by strafing aircraft.
A flak tower consisted of a concrete pillar sixteen to twenty feet high with a circular platform mounted on top. the platform averaged six feet in diameter and had a five foot wall. Usually, these towers had a twenty millimeter or forty millimeter gun mounted on top. Because of the placement of these flak-towers, no two strafing attacks were the same. Ideally, Eighth fighter pilots would fly high over the field as if they had o interest in the target below. The would pick out landmarks to help them line up their attack run and then dive to tree top level. Racing along at 400 miles per hour, they would pop up over the trees, line up on gun emplacements or aircraft, and open fire,. The first wave usually caught Luftwaffe ground personnel and antiaircraft gunners by surprise, while the succeeding waves of strafing aircraft flew through a hail storm of antiaircraft fire. Several leading Eighth Air Force pilots would become prisoners of war as a result of ground fire.
