X-Plane 10.20+ Douglas A-20G Havoc. The Douglas A-20 Havoc was an American attack, light bomber, intruder and night fighter aircraft of World War II. Although not the fastest or longest-range aircraft in its class, the Douglas DB-7 series distinguished itself as a tough, dependable combat aircraft with an excellent reputation because of its speed and maneuverability. The one presented here is part of the 416th Bombardement Group which took off from Wethersfield in Essex. Credit goes to Bernard Augras for using his pilots. By Philippe Gastebois.
