The problem here is that we are ALL (myself included) making some huge assumptions here. It was specifically stated that the guy never did anything wrong, he never busted airspace. The fact that he didn't respond to air traffic controllers trying to contact him wouldn't even get put in a report had he not been a foreigner. He was apparently not REQUIRED to talk to ATC, so what's the big deal there?
Secondly, the CFI said he was weak in his skills. So, who was the CFI, and what's his experience level in that sort of airplane? I once watched a young, inexperienced CFI go fly with a guy who was just flat shit hot with a C 185. The kid wanted to log some "C 185 time". He got it, then came home and told everyone in range that the owner of the plane was dangerous. I'd flown with that 185 owner, as had several others, and we all knew that the guy was as good with that airplane as it gets. He gave the kid a ride. So, should that CFI have called out the military?? Remember, the CFI in this case didn't even have to be rated in the airplane, according to the FAR. So, was this a young CFI looking to log some turbine time and the guy gave him a ride?? Was this CFI even vaguely qualified to determine that the Frenchman was competent in that airplane?
Or, was this CFI an old hand, well experienced in turbine twins, etc, etc?
Problem is, we don't know.
Third, the instructor didn't say the pilot didn't speak English. He said he couldn't speak it well. Okay, who determines what's "good enough"? In this context, please--not in controlled airspace, etc.... We have Air China students flying around here all the time that hardly anyone can understand. I regularly tell my students, however, that those Air China students' English is a WHOLE lot better than my Cantonese speaking skills....

. And, again, we don't know the context. If this Frenchman didn't enter airspace where ATC communication was required, he isn't required to communicate AT ALL. So, exactly where was the issue with language? As it turned out, he didn't violate any airspace, and the FAA clearly stated that he did nothing wrong.
The CFI "thought" he might get in trouble????? Good grief!! That could apply to a lot of folks.
Okay, let's take this to the next level, folks....you've all seen some of the little video clips that members here have posted. So, what if a CFI concludes that this kind of stuff is just plain dangerous????
Again, it is context that's important. Was this Frenchman a threat? Apparently not. Further, he seemed to manage to fly the airplane and land it when instructed to do so. So, again, he must have known something.
Finally, I've seen a few foreigners who actually understood English quite a bit better than they let on. Who knows if this guy was just jerking an arrogant CFI around some.
Bottom line is that without a whole lot more information, I'd say none of us knows what really went on here, and unless you want some clueless CFI (oh, and there are some of them out there folks) calling the Feds every time you post some "risky looking" stuff on the internet, I'd say that a CFI's job is to evaluate, train, and make logbook entries.
If you're a CFI, you have gone through the TSA's "Security Awareness for CFIs" training, I presume?? If we all followed that BS, we'd be calling out the cavalry on all sorts of innocent people ("What do you do if you see an airplane with grass stuck in its' landing gear??? Call the Police, of course" ), and someone who we witness breaking into an airplane on the ramp, we are told by TSA to "contact our Chief Flight Instructor".
If those are the criteria by which this country is to be made more safe, we're hosed, folks.
I say someone needs to go have a serious chat with that flight instructor, and if indeed the CFI has his sh&t together, give him a thumbs up. If it was just some knob trying to cop a little free turbine time, take him out back and thrash him, then send him the gas bill for the fighters.....
Problem is, WE don't know which it is. I think what I'm trying to suggest here is that we all should use some common sense.
