almost always inadvertently by
private pilots.
... *almost* always...???

One of the cases that came closest to a shoot-down was carrying a public
official on official business. I believe this was a commercial pilot.
Of course, he didn't "stray" into restricted airspace, he was supposed
to be there, and "something went wrong".
