Matt, you and I seem to have the same facts, that is that the information on "loiter" came from the SSA website,or the article by SSA, and not directly from the FAA. Our interpretation is different, you seem to believe that this is equivalent to the FAA saying the same thing, and I don't agree.
This case seems to be done and not going to court after the sheriff and local court buffaloed the glider pilot.
But if it did go to court, the prosecutor might have an easy time before a local jury to the effect:
"Folks, this man recklessly flew a airplane over our power plant and homes, without a flight plan on file anywhere, and without being in contact with an air traffic control facility.
And not only that, but he flew very low and without even an engine, with nothing tangible to hold him aloft and he might at any time crash into the power plant or homes below."
The jury is not going to be pilots or EAA members, it is going to be the housewives and retired people of the local area. This is Nascar and tobacco country in a red state, and that is likely the type of people who would be jurors.
And who is going to speak for the glider pilot? Is the FAA going to come down and say that the pilot did nothing wrong? Not likely. And how much weight do you think the SAA witness is going to carry with a jury if indeed the SSA even was willing to get involved, which I have doubts about ?
Perhaps you know of a number of cases where the FAA testified on behalf of a pilot against law enforcement, and if so I'd like to hear of them. I know of a case where the FAA went out of their way for 5 years or so to try to convict an American war hero and renown expert airshow pilot, Bob Hoover and the lack of due process and any semblance of fairness would make an Iranian court blush.
I personally know of a case where the pilot was accused by lawyers for the other side of making a bad and dangerous landing, ie too long and too fast. The pilot would likely have been in trouble if not for one thing, unbeknowst to those lawyers there were photos from a local photographer showing the landing exactly on the aim spot in the middle of the vasi lights.
I don't think it is as cut and dried, (no problem) as you make it out or would like it to be.
