Are three things better than two? Engines? Yes. Beer. Yes. Stool legs? Yes. Wings? Er… no, probably not. However, whilst the triplane idea was abandoned by 1920, it was a widespread aeronautical design before then, being used by pretty much every plane-building nation of the time.
Most notably triplanes were the mainstay of the German Air Force in the First World War, with aircraft such us this extravagantly painted Fokker Dr.1. used extensively (and successfully) throughout the conflict.
This superb small-scale recreation of the Fokker Dr.1 – made famous by the ‘Red Baron’ Manfred von Richthofen – comes form Flickr’s Henrik Jensen, and there’s more to see at Henrik’s ‘Fokker Dr.1’ album via the link above.
