Looks like the account might be back.
X suspended ElonJetNextDay. The version of ElonJet that was delayed by 24 hours to comply with X policies. This account has gone years without issue since the original ElonJet got suspended back in December 2022.

Helicopter with hidden identity using PIA headed to LA, FFL764, hex A03D74. Might be one of Bezo's since its coming from West Texas, but unsure. Would love a spot.

I analyzed the impact of the FAA's ban on simultaneous parallel approaches at SFO, which went into effect on March 31, 2026. The number of TCAS Resolution Advisories (RAs) fell by about 90%.

Some really exciting work I’ve been doing to identify and link FAA Privacy ICAO Addresses to real aircraft. For historical PIA hexes and future hexes.

Can anyone in LA area get the tail number on this aircraft?

We already know N7628 and N8728 are the new SpaceX/Elon aircraft.

But the tail numbers N9728, N3628, and N1628 are also reserved using the same Gulfstream lawyers as the 7628 and 8628.

N7628 routings public for today, the aircraft is not blocked and trackable on FlightRadar24. Would be great to get pictures of this aircraft.

N7628 is currently on a delivery flight from Gulfstream. This new Gulfstream G700 will serve as a secondary aircraft for Elon, joining the G800 (N8628) he received earlier this year.

Caught one of the rare Beechcraft Starships landing at Addison Airport (KADS) today. N723SC (NC-50), owned and operated by AQRD.

One of only a handful still flying and operates under the FAA’s PIA (Privacy ICAO Address) program using callsign STRSHP1. youtu.be/Toz7Uy5d2ds

Jeff Bezos just flew his Gulfstream G700 N11AF from Titusville, Florida after a visit to Blue Origin down to Miami. From there, he transferred to his helicopter and flew from the airport to his home on Indian Creek. The helicopter, N2AF, is operating under a privacy ICAO address to mask its identity

Two DoD Missile Defense Agency (MDA) Gulfstream G550 HALO aircraft (N552HA, N553HA) are currently en route from Tulsa. Both airframes are operating under the FAA's Privacy ICAO Aircraft (PIA) program as FFL1922 and FFL1923, attempting to hide identity. Likely heading to Hawaii.

Taylor Swift's Jet Returns to Service after Major Overhaul
Taylor Swift’s Falcon 7X private jet is back after a multimillionaire overhaul. Now flying as N3200X, see how public flight data still tracks the exact same aircraft.

YouTubers don’t like their private jet being tracked.

N7628 was just reserved for a Gulfstream G700. Looks like Musk will have a G800 and G700
