Wings of Eagles Discovery Center has three replica aircraft (http://www.wingsofeagles.com) in addition to14 actural originals. Two are full size, accurate, exqisitly rendered replicas of WWII German and Japanese aircraft. There is also 7/8, flyable replica of a WWI Nieuport 11. In addition we use large scale and 1/72 to 1/48 scale models in period exhibits. The whole experience is enhanced by the physical and verbal presentation. As for ducuments and photos; copies from archival storage are always safest.
