I believe that David Billings four part treatise on the 'TIGHAR Scientific Methodology' bears repeating in a topic of it's own; not to be lost among many other posts in the topic 'TIGHAR at it again'. Please post your comments after the 4th installment.
TIGHAR and the TIGHAR SCIENTIFIC METHODOLOGYPart OneThe recent propulsion of the Aluminum sheet = "Once More into the Breach" I suppose that the dragging out of this piece of aluminum aircraft skin had to happen when Mr. Gillespie is desperate to invent some new angle in order to appeal to the masses that are not aware of his tendencies, as an angle made to urge them to open their wallets and send him some money to buy groceries. I am told that is about the state he is in at this present time with former major contributors to the TIGHAR Hypothesis refusing to shell out, yet again.
He has publicly anaesthetised The Discovery Channel so no luck there. The recent crowd funder appeal resulted in securing a few thousand dollars only, which must have been quite a blow to whatever value of pride he has left.
We do know that this piece of aluminum sheet has appeared before in
1991 as per these words:
The Bottom Line 18 Oct 1991 ( TIGHAR)"Through laboratory analysis of its physical features, and archival documentation of their significance, Artifact 2-2-V-1 has been shown to be identical, in every knowable aspect, to a particular and unique section of NR16020. At the same time, it has been shown to be unlike any part of any other aircraft known, or even rumored, to have been lost in the region. The conclusion is inescapable. This is a piece of Amelia Earhart’s aircraft."
TIGHAR Bulletin March 12, 1992 claims:"The analysis of artifacts recovered during last year’s expedition has reached the point where we can now say with confidence that we have the proof. Exhaustive research has established that a section of aluminum aircraft skin found on Nikumaroro could only have come from Earhart’s aircraft (see page 2, “Artifact 2-2-V-1”)."
...and we go back a bit for this statement:
"In 1988 TIGHAR set out to demonstrate that high academic standards could replace
wild imaginings with
rational hypotheses, and that strict adherence to
scientific method could
sort fact from fiction to discover the truth about the disappearance of Amelia Earhart. We did it with the hard work and perseverance of the Earhart Project volunteers; the generous assistance of scientists, scholars, and corporations; and most of all, with the support of the people who make it all possible: you, the worldwide members of TIGHAR." (My bolding)
Let us leave these historic words and venture into the Credo which TIGHAR states that it upholds.
The TIGHAR SCIENTIFIC METHODOLOGYThe above TIGHAR statement can be attributed as a precis of what is known as the
TIGHAR "Scientific Methodology" where fact is separated from fiction and every pronouncement made by TIGHAR is made in accordance with the credo of Scientific Methodology. These two words: Scientific Methodology, are used very often to underscore and to mean, TIGHAR's painstaking application of expertise to reach a solid scientific based conclusion. The words appear in statements and in bulletins issued by TIGHAR. We shall see Scientific Methodology applied.
So you have Gillespie saying that he uses Scientific Methodology on the one hand and producing a scrap of sheetmetal with no proof on the other. It could be said that the man is totally without conscience and is prepared to place a grab-bag of bits without any provenance in front of the public and ask for money.
TIGHAR: The TIGHAR Hypothesis.Earhart's last transmission stated that she was "....on the line 157-337, flying North and South". From this, two serving American servicemen postulated that Earhart would not continue flying "north" but would likely have flown "south". It so happens that a the rising sun on that morning, on an azimuth of 067 degrees TRUE, causes a sunline, which if drawn through HOWLAND Island in degrees TRUE (not Magnetic) and continued South-south-east on 157 degrees True, passes close to Gardner Island. Gillespie picked up on this postulation and ran with it, we now have the "TIGHAR Hypothesis", using a 157-337 degrees TRUE, sunline. Note that Earhart did not say "sunline", she said
"line".
The first problem with this is, that you can draw any line on those degree numbers centred at any point East of half-way on Earhart's track line between Tabituaea Island in The Gilberts and Howland Island and you would be about as wise as to position of the Electra as Earhart and Noonan were on 2nd July 1937. If they had known "where they are" on that track line, it could be said that with Noonan's expertise they would have found Howland. The conclusion that can be drawn from that is that they did NOT know where they were on the trackline when they started the approach preparations for Howland.
The approach to Howland was supposed to be a direct DF approach, using a Direction Finder fitted to the aircraft. Some say, Noonan would have used an "offset " approach where he diverts from track at a distance from the target, purposely "aiming off" until reaching a sunline (by a reckoning method) and then turning in towards the target, flying into the target on the sunline. It may have been an approach using both methods.
There is a second problem with this "broadcasted" 157-337 line and that is that the degrees are interpreted as TRUE degrees and Aviators do not work in TRUE degrees, they work in MAGNETIC degrees. If not laying off for wind as they approach close to Howland they should have been steering 068 degrees Magnetic. Earhart did not say she was on a sunline, she said
"on the line" and
a line of 157-337 Magnetic does not go near to Gardner Island. If Noonan told Earhart to steer 067 Magnetic, allowing one degree for wind, then the line 157-337 at 90 degrees to the trackline of 067 degrees Magnetic would be correct for the 157-337
"line"...... a
line at right angles to their steered course.
Even so, if they were flying "North and South" on a supposed pre-planned sunline of 157-337 TRUE degrees, there is absolutely nothing to say that this sunline they were using did cut through Howland Island, after all, they "thought" they were there, but obviously they were not there.
The problem Gillespie has is that the TIGHAR Hypothesis is built on an
assumption. The assumption is that Earhart and Noonan took a south-south-easterly course after not finding Howland Island and eventually wound up at Gardner Island, now called Nikumaroro Island. There is no basis for thinking that Earhart would head off into the unknown, which is exactly what it would be. For in not finding Howland, the conclusion must be that the Navigation under Noonan was not sufficient to find Howland and therefore if they could not find Howland, they were in effect "lost".
They expected and indeed thought, that they were near Howland; as is shown by the radio transmission, "We must be on you but cannot see you", surely one of the most tragic radio transmissions in history. When you are lost and your position is not known, you cannot navigate to a "known" position. We are in the air now, not on land.....we cannot walk back through city streets to get back to where we came from, or ask someone for directions, then start again to get to where we have to go. In the air over the sea, you have to know where you are or by a recent landmark, where you were.
It must always be remembered that Navigators of this period, navigating by Astro Navigation and for many years after, until the invention of Inertial Guidance Systems and GPS giving readings of LAT/LONG; could NEVER tell you "where you are" at a given time, only "where you had been" at a given time. Any position report request from an aircraft Captain of "Where are we NAV ?" would be met with "Well, at 0900 we were at X and by now we should be at Y, I'll give you an update after my next fix." After the next fix meaning that the fix itself had to be worked out to get the position..... where they had been......
The question arises of whether they actually knew that the Phoenix Group of islands, widely spaced in the Central Pacific could be found, rather than the islands that Earhart had nominated as her
Contingency Plan, which were The Gilbert Islands. If they could navigate to Gardner Island, they could navigate to Howland Island, it is that simple. If they do not know where they are on the track line to Howland, they cannot follow a line of position to anywhere.
In order to leave their unknown position and find somewhere dry, it has to be asked: "Which is the better plan ?"
1. From an unknown position on their track line to Howland Island, turn back on their reciprocal course (a reverse course) for the Gilbert Islands; which would be a 500 Mile wide swath of islands at right angles across the return path which would be hard to miss.
or,
2. From an unknown position on their track line to Howland Island, turn SSE for a group of islands, 350 miles away, widely spaced which they could miss, very easily..
They carried strip maps which were about 500mm long and 200mm wide. For the LAE-Howland sector of 2556 Miles, the straight line covered the page from left to right and the tiny islands of the Phoenix Group would be mere pin-points on that piece of paper, with no Lat/Long numbers shown.
They also carried the 1936 National Geographic Map of the Pacific for which there were no Lat/Long numbers given for the Phoenix Group and again, the islands would be mere pin-points on that map.
The choice is simple,
follow your Contingency Plan for the Gilberts. The TIGHAR Hypothesis remains an
assumption, a hypothesis, no evidence that it actually happened. Yet TIGHAR has expounded volumes on the Electra safely landing on the reef, even to the extent of "taxying in under the shade of the Ren Trees" and then being pushed across the island to a supposed "rough runway", then being "washed into the lagoon", then "being washed over the edge of the reef into deep water"....ALWAYS (akin to the hidden pea game) in an attempt to garner more funds to keep TIGHAR alive and well and living in Delaware and now in Oxford, Pennsylvania.
The
TIGHAR Scientific Methodology declares that Earhart was mistaken in her pre-flight Contingency Plan to fly back to The Gilberts and she abandoned
this astute plan (planned for a possible circumstance) and headed off into the Southern Pacific, hoping to make landfall.
Part Two to follow.
