Here is the flight path published in Tosaw's book. The fp crosses at the eastern tip of Hayden Island. It has no resemblance to V23 or any other published flight path including the proposed Eastern flight path which supposedly crossed at the Troutdale airport. For those who recall that was the flight path endorsed by Ralph Himmelsbach and Jerry Thomas.   

Did Tosaw subscribe to this flight path or is it just an gratuitous illustration ?

Again, on page 93, Tosaw labels the dotted line "victor 23 flight path"

And yes, it's a terrible graphic that doesn't give the actual V23 corridor nor does it appear to be based on the FBI map.  The quality of the graphic is immaterial, Tosaw was, for lack of a better term, an orthodox researcher when it came to the flight path.

This is for Shutter:

The Old Man doesn't believe the auto-pilot was used at the time of the jump. "You don't use an autopilot when you're doing something abnormal. Landing gear down, tailgate open is not normal. It Rataczak said he was flying the plane, he was flying the plane."

He also said the "bumps" would look the same whether the auto-pilot was on or whether a human was at the controls. "Both do the same thing, correct back to your line"

Ok, makes sense. they mention adjusting the trim. you wouldn't do that if the autopilot was on...

Yes you would do that in 1971.

All,
I was having dinner with my science friend Bruce the other night and he asked about Cooper. I told him there was a big discussion about the flight path and the placard drift rate. Bruce is retired from JPL, created the first clear air turbulence instrument and was on the team that discovered the ozone hole. He described the boundary layer  over land (as opposed to water) as going from 0-3000 feet or so and it is in this layer that the winds typically are in a different direction from winds aloft. He said the way to answer the question is get the radiosonde data from those dates in that area and it would show the winds from ground to 12K+ feet or so. It turns out that the data is tricky to get and condense into readable form so I had to bribe him with a steak dinner and now we have the data!

The two closest locations were Salem just south of Portland and Quillayute Bruce said was just west of Seattle. They launch twice a day at 5pm and 5am so that is the data we have. I had him pull a second random day Nov 11 for comparison and you can see that the winds then were actually east near the ground. Nov 24 looks pretty consistent all the way down but seems to be more southerly than we had estimated. Now you can do a proper analysis.

It is possible for the winds at surface and aloft to be going in different directions. Generally, as you go up, the direction of the wind direction gradually "spirals", but it's not unheard of for them to be very different.

Which is why I don’t put much value in its location. There’s 7 years of variables that no one knows there.
