Passengers on Japan Airlines Flight 516 were buckled up and ready to land at Tokyo's Haneda Airport as their pilot made a final approach. "Cleared to land," the pilot repeated after receiving an instruction from air traffic control to put the jet down on a specific runway. About two minutes later, the Airbus A350 that traveled from New Chitose Airport near Sapporo was engulfed in an orange fireball on the ground, spewing gray smoke from the side.
