While Jared Mike settled in at the Tracon, pilot Phillip Bush guided the Piper Seneca westward. Despite the strong headwinds, Flight 55 was slated to land at Boeing Field on schedule with its time-sensitive freight. The flight from Seattle to Spokane just hours earlier had been uneventful. Bush knew the weather over the Cascades could change quickly, but the turbulence now buffeting the Seneca was still unexpected. The aircraft jolted as the air roiled off the terrain below. The cargo, bungeed down directly behind Bush's worn seat, strained against its straps. Passing the town of Ellensburg, he coaxed the Seneca upward to 13,000 feet, where smoother air hopefully waited.
