Roger, looks like the TSA is being reasonable about the border overflights during landings at your airport. Not the story here at Grosse Ile (KONZ). One stop was reported to have taken place where a TSA King Air blocked the offending aircraft on the taxiway and the TSA personnel had weapons drawn. I recall getting an email about this TSA stop from a friend who flies out of KONZ but could not find verification of this on any official website before writing this. Last year, my friend attended an EAA informational meeting with guests from Windsor, Canada ATC and Detroit Metro ATC. Each party acknowledged that there were overflights of GA aircraft during landings under VFR flight but that this wasn't a big deal if the aircraft were in voice communication and had Mode C transponders turned on. During this discussion, a TSA person stood up and interrupted the meeting, identified himself and informed everyone that there would be no slack given for overflights and all who ventured into Canadian airspace and then came back in the U.S. would be detained and dealt with.
