Cooper had at least two accomplaces. "A" got on the 727 earlier. Maybe at Portland of a[guess: got] an earlier stop (if any). He was one of the first passengers to get on board so few if any would notice that he had a piece of Carry on luggage which he put under he seat. He was one of the last to get off at Seattle, so that in the confusion no one would notice that he had "Forgot" his luggage. In this luggage there was a pair of jump boots, a specially made jump suit with, pockets, hooks etc to carry Coopers equipment anda sport parachute. The chutes Cooper asked for were just decoys. one of which was thrown overboard in a wooded area somewhere along the line. On the first place he would not have trusted any chute that was furnished and in the second place a sport [guess: schute] is much more manouverable than a standard shute. Also there was a portable OMNI receiver, a flashlite, an al[guess: timeter] and maybe a small comp ass to use if he missed his target, also a small walkie talkie. Some of these items may have been in the case [guess: where] cooper diplayed his supposed [guess: y] "Bomb"
Here is how they plan was ca[guess: rried] out. After negotiation in Seattle Cooper told the pilot where he wanted to go, how high and how fast to fly and what route to take, such as V23, Cooper knew just where this route would lead. Soon [illegible] after the plane was airborn he opened the rear door, let out an antenna for his OMNI receiver and started to moniter the flight. With his OMNI set he could tell exactly if the plane was on the correct path. By monitoring and keeping track of the time from one OMNI station to another he knew the exact speed. With the OMNI indicator he knew exactly when each Vortac station was passed over. If the plane was to one side or the other he could tell exactly how far by recording the time from one angle bearing to another.
