At 18:45 UTC on 7 November 2026, RFS729, a Cessna 172 Skyhawk registered N82MH, began transmitting transponder code 7600, lost communications (nordo), near Seattle (SEA) at 1,000 ft.

The code stayed up for about 15 minutes; we last saw it at 19:00 UTC, by which time the aircraft was at 2,700 ft. The map shows the path flown around the event, colored from live ADS-B positions.

A squawk code is set by the crew on the transponder. 7600 means radio failure: the aircraft has lost two-way communication with air traffic control and is following standard procedures. Nothing here is confirmed by the operator or an investigating authority; it is what the aircraft broadcast.
