▶ Replay 📊 Analyse

SWA1155 (Southwest Airlines) was operating from KMDW to KSEA on 2026-06-21. SkyMeter detected a long landing rollout at Seattle Tacoma International Airport (KSEA) on runway 16R at 19:31 UTC. Trace data at the event: 380 ft AGL, 5 kt GS, 0 fpm vertical. METAR at the time reported 7 kt wind, 7 kt crosswind component, 16,093 m visibility. A long landing rollout is detected when ground deceleration after touchdown is below the per-runway P10 envelope. It is an observational measure of rollout efficiency, not a runway-exit incident. Detection algorithm and known limitations: see SkyMeter methodology.

SkyMeter cross-referenced this flight against FAA-published TFRs that were active during its window and within its geographic bounding box. Overlap doesn't necessarily mean violation — the aircraft may have been outside the TFR’s precise polygon or flying under air-traffic-control coordination.

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.
