KPO77 (Alliance Aviation Group) was operating from KIAD to KBLM (Monmouth Executive Airport) on 2026-04-09. SkyMeter detected a diversion to General Edward Lawrence Logan International Airport (KBOS) on runway 04R at 17:27 UTC. Peak cruise altitude FL354, turnaround area near Orange, US. Approach stability score: 71/100. 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 18 kt wind, 16,093 m visibility. 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.
