A photo and a poster display depicting all the various aircraft and squadrons involved in the Air Defense of North America was started as an ADC exhibit for the Museum. The above photo and posters show only an example of some of the interceptor and support aircraft. Museum Lifetime Member and ADC Historian Marty Isham was solicited to research the information for the above posters. Marty Isham has co-authored books for the F-89 and F-94 and has other books in draft. Marty Isham & Erv Smalley also have a history website for the F-106 that gives the lineage for each of the 340 Delta Darts manufactured. Smaller revised versions of the above posters are available in the gift shop.
