Halliburton

The aircraft is at 40.58°N, -79.88°W heading 166.6° at 220 kt, 4450 ft, likely climbing out of the Pittsburgh area. The only candidate with Δhdg ≤ 90° is KIAD (Δhdg 36°), which is off-track but not behind; all other candidates have Δhdg > 55° and most are behind the plane. KIAD is a recurring destination for Halliburton, and at 149 nm it is a plausible short leg from this position. No ALIGNED candidate (Δhdg ≤ 25°) exists, so confidence is moderate. Past predictions show a pattern of overconfident long-range guesses (e.g., OEDR, YMML) that were wrong; this prediction biases toward a nearby, plausible, recurring airport.
