Question. How does a T-38 fly escort with a PA-28?
They don't. As USAF
Hummer stated, NASA doesn't send up aircraft to intercept airspace violations. That would be handled by the Air Force. I also believe that the T-38's are based at Huntsville. They are used for crew pilot proficiency and they fly them to the Cape shortly before their launch date. And they are never armed. Besides, I don't believe their airspace is tightened up or exceptionally protected until a shuttle is on a pad, and especially on launch date. I've flown thru the airspace several times (with the proper authorization of course) and I've heard a guy get chewed out for entering the airspace without the proper clearance and the controller told him he was "lucky if he didn't have a couple of F-16's out on his wing".
As for an F-16 intercepting, I'd gather that the single's cruise speed is just about at the bottom of the 16's low speed capability (around 130kts) and I'd assume they would 'dirty up' with flaps and gear down, and come alongside and rock the wings.. signalling to the pilot to land. They probably would have to be actually doing a slow pass instead of flying formation, but it would get the point across. The kid who flew his plane into a skyscraper in Tampa in 2001 had a CG Dauphin flying off his wing right up until impact... don't think the 16 could do that.
And Corey, the airspace is as follows...
R-2932 to but not including 5,000' (Continuous)
R-2933 5,000 to unlimited (Intermittent)
R-2934 Unlimited (Intermittent)
R-2935 11,000 to Unlimited (Intermittent)
That's from an older sectional.. can't find my new one atm, but it's a good indication and probably hasn't changed much.
