In my experiences of discussions relating to the case of Cussac in 1967, it occurred several times that when I discussed a particular point, it was argued that I should discuss some other point(s). I want to specify that what follows is neither a demonstration that the object allegedly seen was or was not an helicopter or an alien spaceship or whatever else, and that the following is not an act allegiance to any work or writings of anybody, neither a study of the exactitude of the distances between some stone wall and some UFO, neither an investigation into the case, nor a statement on the value or solidity of the case.
The item discussed here is in no manner a declaration infallibility of mine, they are not claimed to be "scientific", I never introduced myself as "a scientist" nor an "expert" about anything, I am not the puppet of anybody. I do not claim objectivity, I only claim I try to be. I will make note of any remark, correction, addition, comment, under the sine qua non condition that it contains no insults, nothing discourteous, nothing irrelevant, and no questioning of my intents.
It is this claim, nothing more and nothing less, that I challenge here.
The measured distances are in the GEPAN investigation report; the methodology of measurement is explained there, the nature of measurements is explained there. This can be checked by anyone, the source is:
They are on page 13 under "Measured distances (according to sketch 3)". These distances can be verified by the reader in the report, and they are:
| AB: | 5 meters. |
|---|---|
| CE: | 30 meters. |
| CD: | 10 meters. |
| OC: | 82 meters. |
The significances of these letters are clarified with sketch 3 on page 13 of the report, sketch explicitly made by the GEPAN so that the reader understands what these letters A,B,C,D,O,E indicate. This sketch 3, as the reader can check it in the GEPAN report, is as below:
|
This gives us:
| AB: | 5 meters. | Diameter of the sphere. |
|---|---|---|
| CE: | 30 meters. | Distance from the center of the sphere to the edge of the contiguous road, parallel to the hedge. |
| CD: | 10 meters. | Distance between the center of the sphere and the hedge on the line of sight from the boy to the center of the sphere. |
| OC: | 82 meters. | Distance between the boy and the center of the sphere. |
Note: It is understood that AB indicates a diameter, that other letterings are primarily mnemonic, "O" like "Oeil", "Eye" or "Observateur", "Observer", "C" like "Centre" or "Center", D like "Direction" and "E" like "Ecart" or "Eloignement", Distance or Outdistance.
Use a land map or a satellite map or image, trace the road, the hedges, the trees. Define a scale. The simplest is to use: 1 cm = 10 meters; thus, 10 centimeters represent 100 meters and all will fit on an ordinary paper sheet in "Letter" format. But obviously, any scale or paper size will do the job, all you need is to use the correct values.
You get the "terrain"", the map, the background, that is to say this for example:
|
Note: The True North is here, as convention dictates, up the top, and the West on the left.
On a tracing paper, trace a line of 82 meters.
Call the right end of this line O and the left end C.
With C, the left end of the line as center, trace a circle of 2.5 meters ray, it has the AB diameter of 5 meters.
From this same point C, trace a second circle of 30 meters ray, call E the intersection of this circle with the 82 meters line.
From this same point C, go towards the right along the CO line and mark a point at 10 meters and call it D.
You get:
|
Place your tracing paper on the background by using these conditions explicitly given in the GEPAN report:
You get:
|
I am thus very dubitative when it is claimed that I am unable to draw a plan to locate the object seen by the witnesses based on the measurements indicated by the GEPAN investigation.
Note: the reader who would wish, for comparison, see what is the situation of the object according to a "skeptic" author, the only element of localization that I know to have been published by anyone proponent of the thesis that the object was a helicopter, that reader who would wish to see what methodology is used, and its result, will read this page.
