I remember that it was published in Cugle´s , up to a certain year after which the paragraph was deleted ,
---------------------------------
Scan it in and post it as I have been asking you to do for two years.(It is necessary for us to see the actual documents since, on TIGHAR, you have conveniently left out parts of quotes that directly contradict the points
that you claimed the quotes supported. See:
https://tighar.org/smf/index.php/topic,383.msg5129.html#msg5129)
and in Navigators Information Files NIF during WW-II .
You already have that in electronic form so post that excerpt as I have been asking you to do for two year.
-----------------------------------------
So we won't have to hold our breaths, I have attached the relevant pages from the Navigators Information File PUBLISHED IN JULY 1945, EIGHT YEARS AFTER EARHART DISAPPEARED. It mentions an EMERGENCY procedure that required some tables of information for high altitude dip and refraction that Noonan didn't have in 1937. Even with those unavailable tables the derived LOP is only approximate and not accurate
enough to find Howland. The above procedure presumes the lack of an octant so that the observation must be made with the unaided eye. It can only be done twice a day and is dependent upon a clear horizon, no clouds between the plane and the horizon or beyond the horizon at those two critical times. Why would Noonan, equipped with an octant, rely on such a risky procedure (even if he knew about it. Van Asten has produced no manuals showing this prior to 1945)when he could use the normal practice of taking an observation higher than six degrees and then doing the normal sight reduction?
-----------------------------------------------
If not from sunset , how would mr.Noonan have acquired his 159-07-E / 04-33.5-S coordinates of the 0718 announced fix ? I remember that you once said he would have his information by visual aid : flying close to , or over Nukumanu . For that event he would howver ,
reported to be over 159-30-E / 04-30-S , 27 SM eastwards of the fixed coordinates .
I pointed out to you that those are the published coordinates for Nukumanu and that you seem to consider that an island is a geometrical construct, an infinitely small point, but islands are not, they have dimensions. Nukumau is 11 nm long, east to west, and the published coordinates that you refer to are for the easternmost end of the atoll. They passed near the western end.
I already posted today , and these days that when a navigator sees his precomputed sunset-sunrise time-position group come true , het can announce the coordinates , 0718 GMT , before the phenomenon actually occurs , 0719:30 GMT by superficial observation , especially if by making a detour (Choiseul) he initially left the original flight procedures .
I invite everyone to
read Mr. van Asten's published papers with his oddball calculations and theories and you will see that he is now making a complete about face on this point.
