The aircraft track is 23.24°, and KELM sits at bearing 23° with Δhdg 0°, the only perfectly aligned candidate. Distance (51 nm) is consistent with a short final leg from current altitude and ground speed. KELM is the home base, frequently appears in recent flight history, and this flight likely originated from one of the recent departures in the NY/Pennsylvania area. NK53 (Δhdg 4°, 56 nm) is a plausible alternate.
