It is reported in the newspapers that can be sketchy, I agree..the other problem is the placard appears not to be in evidence any longer or wasn't shown to Tom.

I just posted a pic with the placard directing you to the starboard side. the early models might of been on the port side. the ground crew might look and see nothing and be confused until they read the placard directing them to the other side. constant changes and bugs were worked during the first couple years. they don't have placards telling the ground crew the cargo door is on the other side?

All that placard says is that the regular system to lower the airstairs from the outside is on the starboard side. This is not the same system with the break wire. Again, look at the ASA doc which clearly says that system is on the portside of the exterior.
Some men see things as they are, and ask why? I dream of things that never were, and ask why not?

Neither were the hairs in evidence apparently. How about grabbing DNA directly from Cooper's hairs.

You are missing the point...the placard makes no sense being on the port side when the starboard side also has a placard. it dorects you away from the port side completely telling you nothing is there..."airstair emergency exit handle on opposite side of airplane..

A similar door can be seen in the lower left of that photo and a small plate riveted shut that had something there at one point.

Shutter, give me a call to discuss.

Here's a question for experts on the "FBI map".

Does anyone know the significance of the handwritten letters “NC” (abeam Seattle), “NO” or “NB” (abeam Pigeon Springs, Washington), “NA” or “XA” (abeam Salem, Oregon), and “NQ” or “NO” (abeam Eugene, Oregon)?

Hominid explained it years back. If not mistaken it has something to do with the breaks in the piecing the path together into one. if I'm wrong someone will correct..

Has anyone ever tried to apply a percentage chance of DB hitting land as opposed to water?  And if he did hit water, as unpleasant as it would have been, as long as he could swim he could have made it don't you think?  I am not sure how wide the Columbia is?

It was the military "LandNav" grid system.

SMSgt Wally Johnson, in his 2013 interview with the Washington State Historical Society, identified Captain Thomas Spangler as the co-pilot on the "sled test" flight of 01.06.1972.

Question for experts on the sled test flight. Has anyone contacted Captain Spangler, or does anyone know whether he is still alive?

Well, sort of, back at DZ years ago. PLF inventoried the streams and water areas in Clark County, some in the Columbia basin. His interest was possible water routes for the money to Tina Bar. Take the original NWA search map, determine the areas of water vs land mass in each jump zone ... if you have the tools to do this ? The probability of Cooper hitting water vs land goes way up as the flight path gets closer to the Columbia. There are posts about this back at DZ ...

OK, that makes sense if we read the annotations (from north to south) as NC, NB, NA and NV. If I understand correctly, the Military Grid Reference System (MGRS) uses the letters A through V excluding I and O.

In that case, these map references should be preceded by a 2-character code such as 1P, 2Q, 3P etc, as shown in the attachment.

Does anyone have a link to digital versions of the NC, NB, NA and NV quadrangles?

On further research, I believe that these annotations are not from the Military Grid Reference System (MGRS). The MGRS quadrangles for the flight path from Seattle-Tacoma to Salem are ET, ES, ER, EQ (see attachment).

According to my notes, it's the GEOREF system:

Not MGRS

Thanks, got it now. This site converts latitude and longitude to GEOREF and other grids: You are not allowed to view links. Register or Login.

So the four annotations (from north to south) correspond to the GEOREF quadrangles DKNC, DKNB, DKNA and DJNQ.
