QXE2356 squawked 7700 near San Diego (SAN)

At 15:10 UTC on 28 October 2026, QXE2356, an Embraer E175 registered N656QX, began transmitting transponder code 7700, general emergency, near San Diego (SAN) at 1,600 ft.

The code stayed up for about 10 minutes; we last saw it at 15:20 UTC, by which time the aircraft was at 2,400 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.
