Thats not the case
Cooper was familiar with the Boeing 727, also how to fly it, its capabilities and handling tendencies. For instance he knew the plane could land and take off safely with the Aft stairs in the 'down' position (not even the pilots or the traffic controllers at NWO knew this)
So, its safe to assume he knew about Victor23 (the air path from Sea-Tac down to California where the plane would have to route to meet his demand that plane didn't go above 10,000ft) and also the flight path for the approach to Reno, which brings the plane over wide expanses of perfect landing zone area, on to relatively soft sand and desert.
He would be able to ascertain where he was visually (it was a calm night in Nevada on that 7date) and by the plane turning as it made its descent into the approach to Reno
It would be fairly easy for him to land somewhere within a 10 mile radius.
His pick up would be in car waiting somewhere towards the centre of the planned LZ
Those are valid points, the pilots were concerned that they had to leave the rear stairs open but were okayed to land with them open as they didn't know the situation in the rear of the plane, if he was still a board they didn't want to blow up.
The FBI mentioned that he was familiar with the plane, they were pursuing a link with Cooper having possibly been a former employee of Boeing.
Two nagging questions, the money being one of them, it can't be confirmed that the bulk of the money was recovered by the FBI, if it was they never made that announcement but there were off the record innuendo and insinuations that it was recovered but we don't know that, the 8-year-old boy did recover a small part of the $200,000 in decayed bills, all denominations including $1 bills per the FBI that matched the serial numbers of the marked money.
Could he have accidentally dropped the money that was wrapped in the parachute where the money was found and just took the loss and bailed out in the location that you're pointing out just so he didn't get caught but knew he lost the money? Could he have just accidentally dropped a small fraction of it that the boy found?
The FBI documented that they did not feel he was experienced with a parachute but did make a point of saying that it was not a parachute that could be steered, why wouldn't he demand that kind of a shoot knowing that he had a target to meet his accomplice?
Getting back to your original question about electronics, I was 18 years old in late 1971 in my first year of college and was a Stringer with a City newspaper since I began to drive at 16 years old, had my own dark room Etc.
My dad was a ham radio operator and I had been using and enjoying different types of communication equipment and monitoring equipment since 11 or 12 years old in the mid 60s and in high school was very experienced with communication equipment of the day. How would he communicate with his accomplice? I truly don't believe there was anything other than presented here in this thread in terms of small communication devices, just big ones.
I'm curious as no one really knows what happened with this guy, do you have any other information that can be confirmed two ways that lead you to your theory?
I have always been enthralled with this case, again I had other professional careers but did end up as a long time newspaper man and retired as a department editor from a large seven day a week daily newspaper so I'm open to and all ears as to your theories!
Just saw the post with the website. I will take a look at that in a while.
It is interesting that the FBI mentioned in 2016 that this case no longer was being pursued as their resources were needed elsewhere so anybody investigating this now, you're the only ones.
