video taped at the Vence Pass
In September 2001, Joël Mesnard gave me a video
tape made by Patrick L, April 2nd 2001, at the Vence Pass. In LDLN N°: 362
issued in December, J. Mesnard relates the facts :
In the afternoon (2:53 PM), the take-off (fast
and vertical) of a white ball was filmed with a VHS Camescope. The phenomena
can be seen on ten consecutive different sights. The distance is known with
quite a good approximation, which gives a range of the speeding-up.
Extremmly brief the phenomena (apparantely quiet) was not observed right away. The diameter of the ball seems to be of 1 meter.
In october, I meet Patrick L. I often go in the
Nice area to visit my family . Each time I see Patrick . We several times
climbed together over the Vence Pass . I spend many long hours with him and we
both had very interesting conversations. I can attest that Patrick is not a
cheater neither nor a Tale talker .
Simone, UFOCOM' administrator
Report of the video
by the ADV 'Ufocom team (in charge of analysing
visual documents) . Alain DH, Bertrand P, Simone B, Yves D .
"Come and watch a tape that Joël Mesnard
lend me . It's interesting". This is how Simone, our charming
administrator told me about the Vence Pass Video .
It was a rainy evening at the beginning of a
cold fall . Some tragical events had just happened...I was not in the right
mood for analysing UFO documents .
And so what? We in the ADV team, had seen so many
video documents, that were up to now completelly disappointing . We should
stipulate that all information on a video are, generally speaking, difficult
to analyse .
But - Since at Ufocom we are not fast - we are
dedicated . Therefore it wouldn't take me too long to visit Simone at her home
and watch the famous document .
I watched abstractedly the beginning of the tape .
A harsh landscape could be seen, the very rare
trees were leefless (the shot was supposely taken in april). The analysis woul
be very difficult .
"It's here" Simone said, "that you
will see the first object passing in front of an helicopter" .
The level had hanged . We were still at the Vence
Pass, in the middle of a kind of a prairie, and the photographer was following
the evolution of an helicopter . I biefly saw something passing in the
scope of the camaera .
"The trajectory of this object is too regular"
I said, " it's going to be difficult to get something out of it..."
"Wait" Simone answered, "there is
still something interesting..."
On screen, we could see that the helicopter
wouldn't moove, staying at a very low height . It seemed it was lookin
for something . Finally after 10 minutes, it flew away . But the photographer
was still filming the landscape . He finally took a wide shot of the bushes,
that were for a while hidding the helicopter .
The sequence was over . My attention was loosening
a bit and I had seen nothing . While rewinding slowly the picture I saw the
second object : a lighting bowl was coming out of the bushes and was flying
straight toward the sky . That is what it looked like on the screen .
"Fascinating..." I could'nt say anything
else while I was still absorbed by what was going on the screen .
On the contrary concerning my first impression, we
had here so many informations regarding the video . Thus justifying a very
serious analysis .
The Ufocom team is happy now to give you
the results of this analysis . We hope that will take in account this text
with kindness regarding to some of it's possible mistakes . We are
"amateurs" with very few means, who try to give the most serious and
professional work as they can, without any prejudice at all .
The document is made with a VHS <<Full
size>> tape coded in french SECAM . Considering the real but average
image quality, we can say it's probably the copy of a 1st generation'original,
probably SECAM too .
The document apparently made by chance has 3
main sequences :
1 . An <<object>> can be seen behind
rocks, on the ground .
2 . An helicopter is looking for something in a
3 . After the helicopter is gone .
Sequences analysis .
On sequence 1 we can see the very strange "dance"
of an helicopter . The average quality of the images made out from the copy
we have in our possession, make the reading of the license numbers of the
engine impossible . (Perhaps we could identify these numbers from the
original tape) . Knowing the license numbers, would help us to find the
pilot, and, why not, ask him, just ask him what was he doing in such a
desolated landscape .
By the way, we can try to identify the
helicopter itself .
Identification of the helicopter
Helicopter still from the video
With no doubt, the engine is a EADS "Squirrel",
probably a sole turbine. The helicopter seems to belong to the EDF
helicopter's fleet . (EDF = French electricity state company) .
Please note that EDF'engines have in their nose
a system allowing them to work on high voltage lines . It was not the case
of our helicopter.
In the area a private helicopter company named
<<Nice Helicopters>> is based . They also have "Squirrel"
Helicoper from <<Nice Helicopters>>
This time the similitude is amaizing . Besides,
this company is based in a place not far away from the Vence Pass and which
from the disatance is equivalent to the self operating system of the engines
. We can conclude therefore that the helicopter on our video, belongs to
<<Nice Helicopters>> .
Sequence 1 analysis
Let's go back to our video . During this
sequence, an <<object>> flies fast, in a few shots, in front of
the helicopter . The trajectory of the object follows line and it's
spped is constant .
The real sequence takes 8 images . (40 ms x
8 = 320 ms, thus only 1/3 of a second!) . We have reproduced here 1 image
out of 2 .
There is not much to say about the object .
Without any bases, it's impossible to say for instance, if it flies cloth or
far away from the camera objective .
Anyhow, we can admit it flies cloth enough from
the camera objective . Indeed it seems out of focus, the image has a low
visibility since the development is adjusted .
We therefore have here an insect (or ROD)
passing by chance at the same time of the helicopter in the sight scope .
Analysis of sequence 2
Sequence 2, right after the helicopter is gone,
shows a <<lighting bowl>> that after a while, staying on the
same position, suddenly and silently takes off from the bushes which the
helicopter had turned around . The object is out of the sight in only for
We can note two things . First of all, the
object does take off from the bushes, which gives us the scale . Then this
object speeds up so fast, before being out of the camera . The video
sequence will help us to give measures to the movement, in terms of spedd
and acceleration .
Important notes : Dear reader,
please note, it is because, we think the object pops out from the bushes,
that we can give a study with figures herunder . On the contrary, we
couldn't give any suitable estimation . (A sight camera as well as the human
eye, gives only angle informations, as explained in a previous article) .
On the other hand, during the analysis, we will
ignore a dimension-the z oriented camera/bushes' axe-because we can onlys
tudy the projected image on the CCD level of the camera . Whatever, a fast
moove of the object as z would only upraise the already high values...
We will start with the trajectory projected on
the CCD level .Crossing image after image, the position of the object
barycenter and after we compare it with a steady detail of the image in
order not to take in account the camera's movement, we can therefore give
the objects trajectory in x and y :
Looking with the eye the trajectory looked
spherical, wich wassingular . On the graphic scale, we represented in
abscise (x ax) the image sequence number and in ordinate (y ax), the object
barycenter's coordinates, given in pixels .
We can see that the the object doesn't moove
much in x . A polynomial decrease shows that the trajectory in y is a little
bit more complex than a simple spherical object...
Let's now make an evaluation of the object'
dynamics . To give figures of speed and acceleration, we need to scale .
We have considered that the object comes out of the bushes and by the way,
we know that the top of the trees are at ten meters high (we checked it) .
We can thus evaluate the growing of the objectif and make an estmation of
the size of one pixel projected on the image . Then comesthe speed
and the acceleration of the object, an image after the other .
It's amaizing to see that the object goes from
a "0" level speed to 160 meters / second, meaning 590 Km / hour
in only 160 meters / second .
Comments on sequence 2
We first have to make sure that the lighting
bowl is not a video artefact . For instance a spectacular reflexion
of which the image' movement would be induced by the movement from the
camescope' lens . While we carefully study the video, during the sequence
we see that the focal is stable (the zoom is not running) . By the way at
that time the camera is quite unshakable .
This is not a final proof, but we can
therefore think that the object taken by the camera is real .
Then we should face the eventuality,
that we are facing a natural phenomena inducing such a situation
. We for instance think of the lightning bowl or something of the same
Why not ? But what could explain such an
enormus speed up - and steadily growing - that's in this bowl .
We will go on taking under consideration that
we are dealing with an object made by human main kind . The enormus speed
up (up to 186 G) doesn't lead us in that direction . And
mainly, the fast growing of the accelaration of this object in the air,
bothers us, because such a behaviour is far away of our technologic means
. Because if we still can produce such a value of accelaration (in a
canon for exemple), nothing exists on earth - up to what we know now
- that can give <<an accelarated speed up>> to a body .
We will finally have to talk about the ufo
possibility . If and only if we have rejected the three first steps .
The photographer taking the video would have by pure chance taken a
fast ufo take-off .
It seems that the lighting intensity of the
bowl grows as well as it's own accelaration grows up after a
light smoke screen has started . Would that be a propulsion system ?
The study of this video is very interesting .
However we don't have the right to make any errors in the analysis of this
document . Indeed, we are tempted to make the affirmation that the
phenomena taken in sequence 2 has no rationnal explaination . And then
having the irrefutable proof of the existence of a Unidentified Flying
In this context, we can also ask to ourselves,
what was the reason to sea an helicopter staying there just a little time
before the object' take-off . The probability that he was there
by pure chance, and in such a desoalated landscape, is really weak .
Please, think about it ...
