Prove what? The operational span of the Titan I weapon system is easily available. The condition of both the Titan I and Titan II sites is also publicly available complete with photos.
Or do you want me to prove that I was a Titan II launch officer? If that is the case, you are going to be disappointed. I'm not about to post a copy of my DD214 form here.
Or is "prove it" the best rebuttal you can muster?
