That night changed aviation history. It started in Portland, Oregon, when a man walked up to the flight counter of Northwest Orient Airlines. He was wearing a dark raincoat, dark suit with skinny black tie, and carrying an attaché case. He had perky ears, thin lips, a wide forehead, receding hair. He gave his name, Dan Cooper, and asked for a one-way ticket to Seattle, Flight 305. The ride was a 30-minute puddle jump. He sat in the last row of the plane, 18-C, lit a cigarette, and ordered a bourbon and soda. The plane took off and he passed the stewardess a note.
Thirty-five years later there may be a hint as to who took control of the plane, extracted a ransom, and parachuted away — never to be heard from again.
