A page from a confidential World War II pilot training bulletin, 'Common Errors in Making Overhead Approaches,' illustrates correct and incorrect flight paths for executing diving overhead attacks on enemy targets. Distributed to combat aircrew such as those serving in the China-Burma-India Theater, materials like this taught pilots to avoid common tactical errors including overshooting the target's vertical plane, misjudging altitude, and losing sight of the target during high-speed diving maneuvers.
