Using a regular basic transit would probably be enough required. they are not expensive to buy or use. buying a drone with the software is between 3 and 5k for a good unit..then if you hire a company it will be over a grand for there service..

Since the landscape has changed dramatically over the years I'm not sure what a current survey would tell you...

In this day and age, I doubt if anyone still knows how to use a transit.  Using the latest technology is fast, accurate, would cover the entire Tina Bar area and not just a few points.

Given the landscape now I don't see how this would help. the location is underwater..no beach or slope. no distance from the location to the waterline etc..

FJ reports tonight - slope:

•    #62474

"At the TBAR money spot the estimated slope from money spot to the water.. in 1980.
 
slope in degrees,, 5.7 - 6.5
slope % 10 - 11.4  "

That sounds reasonable. Let me check some other files .... later. No explanation from FJ on how he arrives at these numbers ...

Here is D.B. Cooper Part 46 of 46-043 Ingram which relates Ingram calling in to the Portland Office and the nine serial numbers he gave.

Sioux City Sarsparilla
Nesbitt's orange

Raley’s Supermarket seems to be the place to purchase the root beer..most were in California along with Sioux city.. if you are looking for “The Granddaddy of all Root Beers” DO NOT DRINK SIOUX CITY ROOT BEER!  Drink Sioux City Sarsaparilla.

 Nesbitt's became the US market leader of orange soda pop during the late 1940s and 1950s, with advertisements featuring then-unknown model Marilyn Monroe in 1946, and proclaiming itself to be the "Largest selling bottled orange drink in the world". Nesbitt's own brand of orange beverage was surpassed in popularity by Fanta in the late 1960s and then faded in popularity. In 1972

Do we know for sure how Cooper packed the money. Did he use the spare chute as a money bag? Also, do we know that he secured it from his body or did he hang it from a line?

Anything we know from the reports, not conjecture?

No simple answer to this. No, we dont know how Cooper packed the money with certainty. The problem began when the knapsack Cooper requested was not delivered to him. Coop had obviously intended to use a knapsack to house and transport the money. When that failed ....  the following passages apply:

Transcript T1 resumes:

From Crew Interviews:
When Mucklow returned to the plane with the last back pack chute, she saw that the hijacker had one of the small chutes open and was cutting nylon cords out with his pocket knife. He took the nylon cord and wrapped it around the neck of the money bag numerous times and then he wrapped it a few times from top to bottom, and with the same piece (of cord)  he made a loop like a handle at the top. This nylon cord was pinkish in color. He appeared irritated that they hadn’t given him a knapsack for the money as requested, and after trying to put the money in an unfolded parachute, he decided to leave it in the canvas bag (and fabricate a holding line for that, instead).   

Mucklow Interview II:
The plane took off (with the rear door ajar) and she held her ears because of the loud noise from the engines. Approximately four minutes after take off he stood up and told her to go the cockpit and close the first class curtain, and for no one to come back behind the curtain. The lights were out in the rear compartment and she went forward, faced the curtain, (and turned around and looked?) and the last time she saw him he had a nylon cord tied around his waste and he was standing in the isle. Before she secured the curtain she called back and pleaded with him to take the bomb with him or disarm it before he left.
