UAL433 (UMB Bank NA) was operating from KSFO to KSEA on 2025-10-05. SkyMeter detected a go-around at Seattle Tacoma International Airport (KSEA) on runway 34L at 20:56 UTC. Trace data at the event: 567 ft AGL, 147 kt GS. METAR at the time reported 7 kt wind, 2 kt crosswind component, 16,093 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.

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.
