F35LTNG squawked 7700 near Phoenix (PHX)

At 22:15 UTC on 27 October 2026, F35LTNG, a Lockheed Martin F-35A Lightning 2 registered DEFAULT, began transmitting transponder code 7700, general emergency, near Phoenix (PHX) at 1,100 ft.

The code stayed up for about 5 minutes; we last saw it at 22:20 UTC, by which time the aircraft was at 6,000 ft. The map shows the path flown around the event, coloured from live ADS-B positions.

A squawk code is set by the crew on the transponder. 7700 is the general emergency code: it covers anything from a medical issue on board to a technical fault, and most 7700s end in a normal landing. Nothing here is confirmed by the operator or an investigating authority; it is what the aircraft broadcast.
