PORTLAND, Ore. (AP) — A Washington man who ingested methamphetamine before getting on a plane in Seattle and had what a prosecutor called a “freak out” on board has pleaded guilty to interfering with crew members after the California-bound flight was forced to land in Portland. The Oregonian/OregonLive reports Douglas Smyser is expected to face four months on home detention when sentenced. Prosecutors say Smyser was headed to a drug rehab Feb. 13 in Malibu, California, when he ate meth before his Compass Air flight from Seattle. Prosecutors say Smyser paced the aisle and told a crew member that someone had a gun. He was restrained before they landed in Portland.
