How private is private aviation?

Not very.

The FAA hiding private jet details might not stop celebrity jet trackers
The FAA’s new process might not work as expected.

The jets have transponders and people have scanners and pick up airport signals. Everything is registered and universally identified in the air.

The extent to which current or former police officers and others with the law enforcement or political connections to obtain private pilots’ licenses are able to keep the details of their flight and air traffic operations out of view of the general public is debatable.

There are people with no secrets to keep at the golf course who are suddenly surprised when outsiders to their club or those under a certain income level learn of their activities.

Celebrity jet-tracking accounts have vanished from Threads and Instagram
It’s a bad week for the creator of @ElonJet.

Major white collar criminal groups already have this information, whether or not they choose to post if for the popular press. Otherwise, if jets were not easily trackable, there would be a huge theft problem.
