It looks like Elon Musk started using a new program that blocks jet tracking after the man who follows his plane wouldn't take his Twitter account down

The college student who tracks Musk's private jet on social media rejected Musk's offer to remove his account.

Jack Sweeney, the student who runs the jet- tracking account, said that the billionaire applied for a temporary aircraft registration number after he spoke to him about avoiding being tracked. The account has a large following.

I don't know what to do. There was a message from Musk in December.

The billionaire should look into a new FAA program that will allow him to change his flight identification number, according to Sweeney.

The FAA launched a PIA program in 2019. The program allows aircraft owners to apply for a temporary aircraft registration number that is not currently attached to any other plane, which means that celebrities like Musk can fly anonymous.

The program used to have few users. The program could be more popular if jet- tracking accounts like Sweeney's are used. The National Business Aviation Association held a meeting last week.

Every 60 days, aircraft owners can change their registration number. It can be a difficult process. The PIA program is a hassle due to a lot of paperwork, according to Christian Renneissen, Collins' manager for flight deck connectivity.

If the new registration number is tied to the owner, the process would have to start all over again.

"Elon Musk has a plane that he flies out of Texas and then goes to the same airports as other people," Sweeney said.

Sweeney doesn't have to use the incognito registration number to track the private jet. The jet that Sweeney claims is Musk's was flying on May 7 with no callsign, no tail number, but had "PIA" flagged, can be found on the ADS-B Exchange.

The FAA has a free program called the LADD list. The list makes it possible for aircraft owners to avoid being tracked. The list has no effect on the ADS-B Exchange.

Musk is not the only one who tries to avoid flight- tracking accounts. The LADD list includes celebrities like Taylor Swift and Oprah Winfrey, as well as Louis Vuitton CEO Bernard Arnault.
