One of three new planes available through Microsoft Flight Simulator's Local Legends #3 Update. I was privileged to contribute to the cockpit and engine compartment of this project. The Dornier Do J Wal ("whale") is a twin-engine German flying boat of the 1920s designed by Dornier Flugzeugwerke. The Do J made its maiden flight on 6 November 1922. Numerous airlines operated Wals on scheduled passenger and mail services with great success. The Dornier Wal was considered "easily the greatest commercial success in the history of marine aviation".
