I don’t know. This obsession with Musk’s whereabouts strikes me as a little dicey. I get it — there are safety rules. And Musk could charter a jet. But I don’t think making the guy a martyr is a good look.
How does this make Musk a martyr? Any attempt on his life solely based on ADS-B data would require apparatuses that will get law enforcement involved long before it becomes a tangible risk.
You don't think there could be a starry-eyed kid tracking Elon's jet because when he grows up he wants to be just like him? I have a relative that listened to aircraft radio when planes flew over his house. He became a pilot. But kids today don't have radios. They have cellphones.
