As I said, perhaps the aircraft were using PIA codes before. They certainly have been flying recently without them though. That’s easily verified. In any case, getting around PIA is not illegal, and is something the FAA explicitly warns aircraft owners is possible. PIA is just an obfuscation of the ICAO hex code, there’s nothing stopping spotters at airports from tying a new hex code to an existing registration, and there’s nothing spotters like more than a mystery. All entirely within the law. There is no evidence that anyone tracking Musk’s aircraft, including Sweeney, had any desire to cause physical harm to him, nor that they had that effect. > This attempt to deny the criminal nature of an act is disturbing. What criminal nature? Nothing Sweeney or any other flight tracker did was in any way criminal. Not even Musk has claimed that it was.
