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.

You actually checked what’s been going on before I looked. I mostly just let the bot post. The TaylorSwiftJets Reddit is highly active with people who know more than me, they even follow the charters. They noticed Patrick Mahomes jet N84PH flew into NY yesterday.

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.

Some dude is running a massive operation out of 44SC (4 Holes Field) Atleast 2 jets and 6 turboprops. Not sure why you would use PIA on all these out of a private field.

Jack Sweeney @jacks.grndcntrl.net · 24/06/2026

I’ve been told that. The PIA program office has an unwritten policy for heavily tracked users. 1 PIA actively assigned, one on standby, and one pre-assigned. XPDRs exist which have all three strapped and can be changed by discrete switches. PIAs can be rotated on demand rather than 20 days.

Jack Sweeney @jacks.grndcntrl.net · 24/06/2026

As far as I’m aware it’s a dip switch to change and a log book record each time. This this net jets aircraft likely an issue with transponder/switches.

Jack Sweeney @jacks.grndcntrl.net · 24/06/2026

Transponder flipping mid flight, multiple times.

Jack Sweeney @jacks.grndcntrl.net · 24/06/2026

This is what happens when you use PIA and fly across the international and have SATCOM. Identity exposed.

Let me check got it confused.

Recently I found out the PIA A0FDE4 is N412EP. In N Out CEO helicopter. All over LA a lot. At least this is my research, would be cool to get a visual.

Brought back two of my accounts for tracking US Air Force Aircraft including the new “Air Force One” @usairforcevip.bsky.social and @airforcetrack.bsky.social The Twitter versions of these accounts were banned back in 2022

Jack Sweeney @jacks.grndcntrl.net · 23/06/2026

Yes! @usairforcevip.bsky.social and @airforcetrack.bsky.social Will likely update the usernames to be on my domain. Glad to bring these back. Haven’t had them since they got nuked a long time ago.

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%. (cc/ @thisisaaronland.bsky.social)

A two-panel chart titled "KSFO: the end of simultaneous parallel approaches and the collapse in TCAS RAs," plotting data from roughly mid-December 2025 to mid-June 2026. A vertical dashed line intersects both charts, labeled "FAA ban Mar 31 2026."
Top Chart: Titled "Simultaneous parallel approaches per day at KSFO." It displays a blue line representing the 7-day average of approaches. Before the ban, the daily approaches fluctuated heavily with a "before-ban avg 45/day." Immediately following the March 31 ban, the line flatlines to an "after-ban avg 0.0/day."
Bottom Chart: Titled "TCAS Resolution Advisories (RAs) per day at KSFO (approach corridor + field)." It displays a red line representing the 7-day average of RAs. Before the ban, RAs occurred frequently with a "before-ban avg 2.6/day." After the ban, the line drops significantly to an "after-ban avg 0.3/day."
The bottom left corner cites the source as "airplanes.live ADS-B data."

The jets are usually the easy ones to identify, but change codes. Smaller general aviation harder to identify but rarely change code if at all. I’ve also created www.reddit.com/r/FAAPIA

Jack Sweeney @jacks.grndcntrl.net · 19/06/2026

Of the 900 I’ve logged I have 300+ linked. Total real used PIA codes by FAA after filtering the 2-3k should be less then 1k. The FAA PIA address pool is 50k addresses.

Jack Sweeney @jacks.grndcntrl.net · 19/06/2026

I have about 900 hexes I’ve logged since 2022/23. Going back it seems about 2-3k hex codes have been used all time since 2019. This includes erroneous data, hexes that don’t have real flights or miscoded transponders.

Jack Sweeney @jacks.grndcntrl.net · 19/06/2026

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? www.flightaware.com/live/flight/... globe.theairtraffic.com?icao=a094fa&...

Jack Sweeney @jacks.grndcntrl.net · 13/06/2026

Let me see if it’s updating might be an issue.

Jack Sweeney @jacks.grndcntrl.net · 12/06/2026

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.

0143

Jack Sweeney @jacks.grndcntrl.net · 11/06/2026

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

Jack Sweeney @jacks.grndcntrl.net · 11/06/2026

N9628, is actually pending also.

Jack Sweeney @jacks.grndcntrl.net · 11/06/2026

Some of these used by SpaceX…

This brings us to N628TS G650 N272BG G550 N154TS 737 N8628 G800 N7628 G700 Oh also a helicopter

Jack Sweeney @jacks.grndcntrl.net · 10/06/2026

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.

N7628 took off from Gulfstream fac in GA

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.
