Long landing rollout — SWA1221
KDEN · 35R2026-06-28 22:17 UTC· KBOS → KDEN· SOUTHWEST AIRLINES CO· B38M
SWA1221 (Southwest Airlines) was operating from KBOS to KDEN on 2026-06-28. SkyMeter detected a long landing rollout at Denver International Airport (KDEN) on runway 35R at 22:17 UTC. Trace data at the event: 5318 ft AGL, 6 kt GS. Approach stability score: 76/100. Scores in this band are observed on roughly 25% of approaches at this runway: one or more gates outside the per-runway tightest envelope, but still inside the typical operating range. METAR at the time reported 11 kt wind, 11 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.

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.
