D.B Cooper was on flight 305 when he gave the flight attendant the letter that told her that he had a bomb.
Have a good night.
The flight attendant went to the pilot to go and tell him what D.B Cooper said in the note.
We are almost at Mexico
The pilot told the flight attendant to sit with him and gather more information about the bomber.
The flight attendant goes back to the pilot and told him that she saw a bomb in the man's briefcase and that the man told her that he wanted $200,000 in 20's. The pilot told her to drop everyone off and then they will give D.B. Cooper the money.
D.B. Cooper told the pilot to go to Mexico and to fly the plane in a certain way. Also, D.B. Cooper told the pilot to give him 4 parachutes because he was going to hold 3 flight attendants captive. But, what the pilot didn't know is that D.B. Cooper wasn't actually going to hold 3 flight attendants captive, he told him to give him 4 because in case they do give him a decoy he will have another one.
D.B. Cooper settled himself while they were in Mexico and jumped into the night out in the sky. All the crew members just saw the bright red button flash and new that he has jumped. Later that night, the FBI was looking for him at night and the next couple years, but D.B. Cooper was never found. D.B. Cooper has left his black tie on the plane and the three parachutes.
