Current heading 250.71° aligns almost perfectly (Δhdg 4°) with KPHX at 496 nm, and the plane's recent flights show repeated visits to KPHX including as the immediately preceding stop before East Coast trips. Past predictions consistently erred by guessing transatlantic or East Coast destinations when the actual destination was KPHX, so I correct that bias. KHND (Δhdg 23°) is the only other aligned candidate but further and less directly in the track. Confidence is high because the geometry, range, and recent history all converge on KPHX.
