LXJ509 (Laporte Andrea B) was operating from KJAC to KFSD (Joe Foss Field Airport) on 2026-07-20. SkyMeter detected a diversion to Westchester County Airport (KHPN) on runway 16 at 22:43 UTC. Peak cruise altitude FL475, turnaround area near Denver, US. Approach stability score: 84/100. 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 7 kt wind, 4 kt crosswind component, 16,093 m visibility. 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.
