So the old R&D/presedential hanger will be closing in October to facilitate the move to the new building 4. I for one find the old hanger magical. It feels like you are walking into a secret time capsule filled with all the exotic test planes you have always found so neat. You can walk right up to, and under and around just about everything. The modern hangers are no doubt more efficient, allow for more spread out displays, but are quite sterile, and have about 1% “charm” of the old hanger. See it while you can. I must admit I much prefer old dusty, musty hangers than shiny, sparkly, sterile museums.
