D. B. Cooper

Flight attendants noted that Cooper was very well dressed and never took off his sunglasses (1). Before announcing he had a bomb in his attaché case, he calmly ordered a bourbon (2), then later asked for a second one. After his ransom demands were met, Cooper removed his tie (3), opened the door at the rear of the plane (4), and parachuted into the night (5), never to be seen again.
