UAL2179 (United Airlines) was operating from KORD to KSFO on 2025-12-25. SkyMeter detected a go-around at San Francisco International Airport (KSFO) on runway 19L at 05:30 UTC. Trace data at the event: 162 ft AGL, 121 kt GS, 0 fpm vertical. METAR at the time reported 17 kt wind, 10 kt crosswind component, 11,265 m visibility. A go-around is a discontinued landing approach in which the pilot adds power and climbs back to a safe altitude before re-attempting the approach or proceeding to an alternate. It is a routine safety response, not an emergency, and is taught as the standard reaction to any unstable approach. Detection algorithm and known limitations: see SkyMeter methodology.

All events on this flight
Automated analysis. Events shown on this page (such as go-around, unstable approach, or runway events) are heuristic classifications produced by algorithms from publicly broadcast ADS-B data. They are intended to surface flights of interest for further review — they are not findings of fact, and they do not determine pilot fault, regulatory compliance, or the cause of any occurrence. Coverage gaps and sensor noise can affect accuracy. Only the relevant civil aviation authority or accident investigation body can make official determinations.
