X-Plane 8 And 9 Blohm and Voss BV 141. The Blohm and Voss BV 141 was a World War II German tactical reconnaissance aircraft prototype. It is best remembered as the most asymmetrical aircraft to have ever flown. The BV 141B had the starboard tail-plane virtually removed to improve the rear-gunners field of view. Thanks to Dataroots for the sound files, Scooter for the pilot figures and to Ho-Hun for custom instruments. By Jacques Brault.
