Sadly, it's never going to Happen. Date on the article is 2010. When Collings tried to do an end run through Congress like they did with ther F-4, USAF blocked it with their own Congresscritters, then went on to permanently destroy EVERY Surviving Airframe and Engine, even those in Dayton, and at Eglin. They Saw-cut the tops off the main wing spars. Can't see it with the panels on, but they were one-piece Forgings that cannot be replicated today. They also spiked the High-pressure compressor sections of every Engine. Again, EXTERNALLY they look fine, but they'll never turn again. It's been an ongoing topic of discussion on the Facebook Thud pages, every few months someone brings it up, and the whole tale is told. I'll try to find my copy of the write up tomorrow, and post it.
