Here's an excerpt from that article:
An accent-less, middle-aged, white male in a dark suit and tie, Dan Cooper drew little attention boarding the flight. After the jet took off, Cooper handed Florence Schaffner a note. In the sixties and seventies, men traveling alone commonly slipped phone numbers or hotel room numbers to flight attendants, so Schaffner placed the note in her pocket and ignored it. The next time she passed, Cooper motioned for her to come closer. He told her that she better read the note and warned that he had a bomb, nodding towards his suitcase. Schaffner went to the galley to read the note. She showed it to the other flight attendant and together they hurried to the cockpit to show the pilot. After he read the note, the pilot immediately contacted air traffic control. They in turn contacted the Seattle police, who informed the FBI. The FBI placed an urgent call to the airline’s president, Donald Nyrop, who demanded that they comply with Cooper’s demands. Doubtless, Nyrop wanted to avoid any negative publicity that such a disaster would bring.
