The FAA has issued a NOTAM warning airlines to be careful flying near Central America due to "military activities and GNSS interference." "POTENTIAL RISKS EXIST FOR AIRCRAFT AT ALL ALTITUDES."

A Gulfstream G700 destined for the U.S. Coast Guard, tail number C104, is currently conducting test flights. It is one of two G700s on order by the Coast Guard.

I never planned to build an ADSBExchange alternative, but after it was sold in 2023, I was effectively forced to.

It’s been on the back burner, but TheAirTraffic now has a new main page, and I’ll be launching a user friendly replacement for the tar1090 tracking page soon.

“Most business jet operators don’t use the busiest commercial airports,” says NBAA.

That ignores the fact they still fly in the same airspace and talk to the same ARTCC controllers as the airlines once airborne. Many business airports sit right next to major hubs still adding to traffic.
FAA prohibits most private jets at 12 major airports amid shutdown's air traffic staffing problems
The new restrictions come less than a week after the FAA ordered commercial airlines to cut flights due to air traffic controller staffing shortfalls.

Rumors that UPS MD11 fleet has been grounded are currently supported by ADSB and schedule data; no brown MD11s are flying at the moment - at least six should be airborne to SDF from SJU, TPA, MIA, DFW, MIA, and MSP right now.

FAA seems to have increased the recycling of PIA ICAO codes. For ADS-B privacy. Or wondering if this is related to the Goverment shutdown.

NK1300 and AF1 had a bit of an "encounter" today-- ATC was reportedly yelling at NK1300 to get their attention to get them to alter course. Not sure it was a "close call" at all, but since AF1 involved.. I tend to believe the yelling part.

Thanks to @petchmo.bsky.social for his help in..

I gotta give Swift credit her jet hasn’t flown in ages. She’s just using charter jets though to hide from tracking.

Salesforce CEO Marc Benioff’s Gulfstream G700 private jet just took off from San Francisco and is headed to Hawaii, using the Privacy ICAO Address program in attempt to hide his flight. This comes right after Salesforce announced 4,000 layoffs and a significant drop in stock prices this week.

Reports out that a helicopter crashed in the Hudson river at 3:15PM ET

From my analysis the helicopter in question is N216MH, a 2004 Bell 206 owned by Meridian Helicopters, but leased out.
