Yes, I've seen it. There is very little doubt that the 707 was at Salman Pak and that it was use for terrorist training.
What is missing from all of this is any evidence at all that any of these "trainees" did anything after they were trained but go home to their mommy. I have never seen anything that identified any known terrorist as having been trained at Salman Pak. If the evidence exists it remains classified. If it is classified I am wondering why. There is no obvious reason.
