    No, I am not. I am saying his drone was trespassing on the property.

    Drones cannot commit criminal trespass. From Kentucky law:

    511.070 Criminal trespass in the second degree. (1) A person is guilty of criminal trespass in the second degree when he knowingly enters ...

    A quad-copter is not a person, and the person who flew it did not enter until after the quad was shot down.

    What does all of this say - the Supreme Court has ruled you own at least 83 feet above your property.

    No, they ruled that an aircraft at 83 feet above some property that was causing significant damage to the owner's use was in violation. It did not rule that every aircraft at that altitude is invading the property. I think it is reasonable to assume that had the aircraft in question been causing no disturbance at all the ruling would have been different.

    As others pointed out already, if that would be real, the pilot would have absolutely no idea who shot the drone down.

    Just by looking at the video, no. You do realize that there is GPS in the aircraft that says where it was when it was shot down, and things called "maps" that let people plot GPS coordinates to see where that is, and then when you drive up to the site and see someone with a couple of guns holding the pieces, who freely admitted shooting the quad down, I think you can be relatively sure who did it.

    And that the quad was probably in line-of-sight for the pilot who was using it to take pictures of a friend's house, so he saw it when it was shot.

    Furthermore, initial claims of missing the SDcard notwithstanding, the image quality is so poor that it's hard to believe it came from a 1.8k drone.

    If the SD card in the camera is removed, the only remaining video is what was recorded over ... the wireless data link. That video isn't intended as production quality output, it's for monitoring the camera as it records.

    It CLEARLY interfered with the land owners use and enjoyment of his land.

    It clearly did not, and clearly not "substantially" -- which is an important word in the material you quoted.

    Twenty-two seconds is not "multiple passes", and your ranking of that as substantial fails the reasonable man test.

    A part of the material you failed to quote says that the land owner is due compensation for an infraction, not that he has the right to shoot whatever he wants out of the sky 'cause he's afeared of terrorists.

    The drone owner did not set foot on the shooter's property until after the drone had been shot down. You're using a later act as justification for one that came earlier? No, you don't get to do that.

    Wrong.

    And air planes aren't allowed below 1000 feet over populated areas.

    This wasn't an airplane, it was a helicopter. Helicopters do not have the 1000' foot floor.

    None of the regular aircraft exemptions apply since they are for higher altitudes.

    Exemptions from what? The FAR? Helicopters don't need exemptions from the FAR for low altitude work because the FAR allows it.

    This drone was obviously (from the video) well below that.

    It was within navigable airspace at an altitude that it could make a safe landing without undue hazard to people on the ground. That's what the law requires.

    I love how people say artificial sweeteners are harmless, but whenever I accidentally ingest one I get a headache, become nauseous, a sharpness around my heart, and almost vomit.

    I'm sorry you have a bad reaction to an artificial sweetener, but you should realize that the term "harmless" doesn't mean "nobody can ever have anything bad happen", it means that for normal people it does no harm.

    For most people, peanuts are harmless. For most people, a bee sting is an annoyance. For most people, shellfish are a yummy treat.

    For most people, aspartame is a harmless sweetener. For people who have phenylketonuria (PKU) it can kill them. They lack an enzyme that processes phenylalanine, an amino acid (building block of proteins) that is part of aspartame, and is also found in higher concentrations in turkey. Should the media report on a regular basis this fact?

    For most people, most medications intended to treat some symptom or disease do just that and nothing more. But read the contraindications or side-effect lists and see that some people don't have the same reaction that everyone else does. Does that mean the drug or whatever should be banned? Of course not.

    That's part why I suggested formatting and then sending it back, if the method of couriering the media is secure then the originating party can inspect the flash (as formatting isn't terribly thorough)

    And just what good to the customer is it if you inspect a formatted USB stick and find nothing on it? I suppose you did a full byte-level dump on it before sending it and are going to compare to see if any of the blocks outside the filesystem management ones are different. And if you find something, does that just mean that the system wrote a file to it, or is it a sign of infection? Do you call the customer in a panic, just to have him tell you "yeah, we copied the system log files onto it since we were there and had the space on the stick"?

    but formatting it might stop the malware from actually executing on a random third-party's computer if something happens and the media is lost.

    Why is that the vendor's problem?

    I'm a bit disappointed in the lack of PROM options these days. It seems like it's making this more difficult than it used to be, especially with the demise of conventional serial and parallel.

    What makes you think "conventional serial and parallel" can't be used to download malware? And PROM is cheap, but why would you think that PROM can't be used to install malware?

    The only safe way is after the USB stick is used, is to destroy it.

    If you can't trust your vendor to not send you malware on a USB stick, you don't put it into the airgapped system in the first place, and then you find a different vendor. So I guess "USB stick" as a way of getting data into an airgapped system is not acceptable. That would seem to apply to other methods of entering an update except, perhaps, getting a printed sheet of paper with source code on it. You first have your programming experts look through the source code, then they type it in and recompile.

    Also, always assume that your airgapped network is infected.

    Then you have to always assume that anything the vendor sends you with an update is infected and you can't do updates. "Encyption" gets you nothing, nor will signatures or checksums.

    I think you have to figure out the level of security you're trying to achieve, and I don't see in the question being asked that there is any special security concern involved, only that the system to be updated is not online. There are any number of reasons for that besides "we're running mission critical top secret stuff on it."

    In any case, a vendor requiring that the customer format and return the USB stick is ridiculous. USB sticks cost so little these days that managing such a system will eat up any cost savings very quickly, and if the customer doesn't want to format it then what business is it of the vendor? I commented on a VENDOR requirement, not what good practice for the customer might or might not be.

    Free clue: if you don't want the user to get the update, don't send him the files. Why bother with a password?
