Cas d’Ahuntsic, 26 juin 2015 : résolu. (+ les types de ballons)
Nous présentons ici un cas instructif d’ « objet volant non identifié » filmé de jour. Après six semaines, cette vidéo, qui a d’abord été présentée comme étant « sous analyse », nous renseigne sur l’incompréhension du public face aux phénomènes ovni. On peut remarquer que la vidéo a été vue près de 2000 fois, que 11 personnes l’ont aimé, que 0 personne ne l’a pas aimé, et qu’aucun des commentaires n’a résolu ce cas. Or, ce cas n’est manifestement pas un ovni pour plusieurs raisons :
- les mouvements de l’objet ne sont pas autonomes ;
- l’objet ne fait aucun mouvement ‘typique’ des « vrais ovnis » (zigzag, accélération rapide, virage à 90 degrés, etc.) ;
- la trajectoire de l’objet est en descente lente et constante ;
- l’objet tourne sur lui-même comme un simple ballon à l’hélium mû par le vent.

EXIF Vide.
Observation visuel :
Objet métallique en régression constante suivant une trajectoire stable.
Observation audio :
Voix des témoins, bruit d’avion et bruit inconnu synchro avec le focus de l’objet?
Tâche :
Déterminer la nature de l’objet, déterminer l’origine du bruit.
Outils :
ADOBE Première pro CS6
Ce programme me permet de lire les informations incrusté dans un document, ils sont inscrits par l’appareil qui enregistre. De plus, il me permet de visionné un enregistrement à temps réel, image par image et d’effectuer des agrandissements.
Observations techniques :
Le document présente une anomalie importante, bien que le document ne soit pas l’original du fait qu’il ait été renommé, il ne comporte aucune information EXIF. (EXIF, Exchangeable image file format,
SOURCE : https://fr.wikipedia.org/wiki/Exchangeable_image_file_format)
Cela remet en doute que l’appareil soit un téléphone intelligent puisque par fonctionnement normal les informations EXIF aurait dû être remplis, donnant accès au donné GPS, type d’appareil, lentille, marque, model, etc.
La date de création du fichier ne concorde pas avec la réalité ce qui m’emmène à présumé que ce serait un appareil photo compacte multifonction ce qui expliquerais bruit inconnu synchro avec le focus de l’objet. Le bruit serait le moteur qui tourne pour faire le focus automatique. Ceci ne limite en rien l’observation.
Sur un appareil photo numérique nous pouvons configurer la date actuel ce qui ne semble pas être fait puisque le deuxième vidéo présente les même anomalies (Date de création par l’appareil 12/31/03 19:00:00). Selon le visuel, si la localisation est Québec 31 décembre 2003, il devrait y avoir de la neige et temps froid. Si non, la localisation serait en dehors de la province Québec ou tout simplement du Canada.
Le visuel :
Les captures d’image pourrons déterminer si l’objet est connu ou inconnu. Pour chaque théorie il y aura un exemple vidéo ou photo pour le comparatif.
Théorie personnelle :
L’objet semble être un ballon sonde aluminium en pleine descente de l’atmosphère. Les ballons météo ou ballon sonde son habituellement des ballons latex à usage unique. Dans le fonctionnement normal le ballon latex est gonflé par un gaz plus léger que l’air, suite à son remplissage, il peut atteindre une altitude d’environ 30km après 2 heures d’ascension et explosé dans la haute altitude du au changement progressif de pression. Dans la majorité des cas le ballon sonde ou météo est accouplé à un petit parachute pour amortir la descente des équipements météo ou multimédia attaché au ballon. Dans le cas d’un ballon en aluminium (feuille d’aluminium mince comparable à du tissu), le ballon n’explose pas mais redescend lentement en tournoyant sur lui-même, le gaz laissant place à l’aire à mesure qu’il se vide de gaz. À noter que le ballon aluminium se fissure comparé au ballon latex qui prend de l’expansion et éclate.
Donc, pour ma part je prône la théorie du ballon sonde en aluminium ou tout autre matériaux qui réfléchis la lumière. La trajectoire de l’objet semble suivre une ligne verticale descendante et tournoyante sur lui-même.
Voir l’image en exemple.
Voir aussi la séquence YouTube : https://youtu.be/ywgCs1nt4aQ pour faire un comparatif de deux objets similaires.
Exemple :

Pour la localisation même si elle est inconnue, il est facile de déterminer la proximité d’un aéroport, un aéroport d’importance comme Mirabel, Jean Lesage ou Pierre-Elliott-Trudeau.
Ceci apporte une piste sur la nature de l’objet relié à l’aviation ou météorologique.
Ce qu’indique cette théorie comme étant la plus plausible est le fait du temps de descente de l’objet presque en ligne droite et constante. Nous pouvons en avoir un aperçu dans la séquence à proximité des feuilles d’arbres. (Dans le vidéo 2:19 )
Image d’exemple des autres type de ballons sonde et/ou météo.

1 – Le Ballon stratosphériqueLe ballon stratosphérique est une membrane étanche de latex dans laquelle est emprisonné de l’hélium, plus léger que l’air. Au fur et a mesure de son élévation, celui-ci gonfle jusqu’a exploser, faisant redescendre la nacelle. Il existe également des ballons ouverts constitués d’une enveloppe légère permettant à l’hélium de sortir au fur et à mesure. Le ballon stratosphérique est un aérostat avec un volume très important d’une enveloppe pouvant aller jusqu’à 1 200 000 mètres cube. Ce ballon a pour unique but de servir la science, il est très utilisé par la cnes car c’est le seul ballon capable d’atteindre la stratosphère, il peut ainsi atteindre un plafond de 40 km pendant 24h et peut soulever une charge de 3t. Le gaz utilisé est l’hélium, ce fut le procédé utilisé pour notre projet. Source : http://space-staff.wix.com/stratoz-project#!pq-un-bs/c24br |
Selon le site http://space-staff.wix.com/stratoz-project#!pq-un-bs/c24br voici les noms des types de ballon.

2 – La montgolfière infrarougeLa montgolfière infrarouge (aussi connu sous le nom de MIR) à une enveloppe en aluminium qui permet l’entrée des rayons infrarouges du Soleil dans le ballon chauffant ainsi l’air chauffe à l’intérieur de celui-ci. Il à été mis au point par le CNRS en 1977. L’intérêt de ce type de ballon est sa longue durée de vie, il peut rester en l’air plusieurs mois, la nuit il capte par sa base transparente le rayonnement infrarouge émis par la Terre. Son seul désavantage est son lancement qui s’effectue par hélium. Source :http://space-staff.wix.com/stratoz-project#!pq-un-bs/c24br |

3 – Le ballon auxiliaireLe ballon auxiliaire permet de faire décoller correctement les ballons stratosphérique. Il est souvent de forme tétraédrique et permet de supporter la charge utile lors du lancement. Source :http://space-staff.wix.com/stratoz-project#!pq-un-bs/c24br |
Capture d’image de l’objet
Voici les images que j’ai pu récupérer qui représente les images avec un focus le plus proche d’une image net. La forme est soit ronde ou ovale :



Looking through the archives suggests this site has been doing this for a while at this level, and a look at trenchtwist confirmed the long term consistency, sites that have maintained quality across years rather than just a recent stretch are sites with serious editorial discipline and this one has clearly been at it for a while.
Reading this site over the past week has changed how I evaluate content in this space, and a look at supportnexus extended that recalibration, the standards I bring to reading on the topic have shifted upward as a direct result of regular exposure to this kind of work and that shift will outlast any single reading session.
Glad to find a site whose links lead somewhere worth going rather than back to itself for SEO juice, and a stop at cozyhomestead kept that generous outbound feel, citing other peoples work with real respect rather than just for ranking signals is a sign of an honest operation worth supporting going forward.
Quietly the writers approach to the topic differs from the dominant takes I have been encountering, and a stop at deliverynexus extended that distinctive approach, content that maintains a different perspective without explicitly arguing against the dominant ones is content with confident editorial identity and this site has that confidence throughout pieces.
Reading this felt productive in a way most internet reading does not, and a look at brightcanvas continued that productive feeling, sometimes the open web feels like a waste of time but sites like this remind me why I still bother to look around rather than retreating to old reliable sources for everything I need.
Reading this post made me realise I had been settling for lower quality elsewhere, and a look at moveforwardintentionally extended that recalibration, content that exposes how much I had been accepting in adjacent sources is content with calibrating effect on my standards and this site is performing that calibration function across topics for me reliably.
Reading more of the archives is now on my plan for the weekend, and a stop at actionoverhesitation confirmed the archive worth the time, the rare archive worth a dedicated reading session rather than just casual sampling is the rare archive of serious work and this site has clearly produced enough of that work to warrant the deeper exploration.
My usual pattern is to skim and bounce but this site has reset that pattern temporarily, and a stop at discountnexus maintained the slower reading mode, content that changes how I read is content with structural influence and this site has clearly nudged my reading behaviour toward something better at least for the duration of these visits.
Probably the best thing I have read on this topic in the past month, and a stop at fitnessnexus extended that ranking, the casual ranking of recent reading is informal but real and this site has been winning those rankings for me on this topic specifically over the last several weeks of regular reading sessions.
Most posts I read end up forgotten within a day but this one is sticking, and a look at fitnessnexus extended that lingering effect, content that survives the immediate moment of reading rather than evaporating is content with genuine retention quality and this site has been producing memorable pieces at a rate notable across my reading.
Reading this prompted me to dig out an old reference book related to the topic, and a stop at goldenbarrel extended that connection to other sources, content that connects me back to my own existing knowledge rather than asking me to forget it is content with continuity and this site has that continuous quality.
Reading this confirmed something I had been suspecting about the topic, and a look at buildforwardtraction pushed that confirmation toward greater confidence, content that lines up with independently held intuitions earns a special kind of trust and I will return to writers who consistently land that way for me without overselling positions.
Skipped the comments to avoid spoilers and came back later to find them genuinely worth reading, and a stop at visualharbor extended that surprised respect, when the discussion below a post matches the quality of the post itself you have found something special and this site appears to attract that kind of audience.
Now feeling the quiet pleasure of finding writing that takes itself seriously without being self serious, and a stop at strategylaunchpad extended that subtle pleasure, the gap between earnest and pretentious is fine and this site has clearly chosen to land on the earnest side without slipping over into pretentious which is impressive.
Reading this confirmed something I had been suspecting about the topic, and a look at strategyforwardpath pushed that confirmation toward greater confidence, content that lines up with independently held intuitions earns a special kind of trust and I will return to writers who consistently land that way for me without overselling positions.
Reading this gave me a small refresher on something I had partially forgotten, and a stop at growthacceleratesforward extended the refresher, content that strengthens existing knowledge rather than just adding new is content with a particular kind of consolidating value and this site is providing that consolidating function across multiple visits.
Skipped the social share buttons but might come back to actually use one later, and a stop at calmretreats extended that share urge, content that triggers genuine sharing impulses rather than performative ones is content that has actually moved me and not many posts in a typical week do that for me actually.
Probably one of the more reliable sources I have found for this kind of careful coverage, and a look at signaldrivenaction reinforced the reliability, the small group of sources I would describe as reliable for a given topic is curated carefully and this site has earned a place in that small group through consistent performance.
Started reading skeptically because the headline seemed overconfident, and the post earned the headline by the end, and a look at buildtractionnow continued that pattern of earning its claims, sites that can back up their headlines without overpromising are rare and this one has clearly developed editorial calibration on that front consistently.
Glad to have another reliable bookmark for this topic, and a look at growthnavigationpath suggested several more pages I will be marking too, building a personal library of trustworthy resources is one of the actual rewards of careful browsing and this site is earning a place on my permanent shortlist for the topic.
Closed the tab with a small sense of finality rather than the usual rushed exit, and a stop at signalcreatesmovement produced the same considered closing, when reading ends with deliberate satisfaction rather than impatient skip you know the time was well spent and this site is producing those satisfying endings consistently across what I read.
Now setting this aside as a model of how to write thoughtfully on the topic, and a stop at festiveglow extended that model status, content that becomes a reference for how a kind of writing should be done is content with influence beyond its own readership and this site is reaching that level for me clearly today.
On reflection this is the kind of writing that improves my taste for what is possible in the format, and a look at actiondrive continued raising that bar, content that elevates my expectations rather than lowering them is doing important work in calibrating my standards and this site is participating in that elevation reliably.
Really like that there are no exclamation marks or all caps shouting throughout the post, and a quick visit to focuspowersmovement maintained the same calm voice, restraint in punctuation signals confidence in the content and this site clearly trusts its substance to do the persuading rather than relying on typographic emphasis.
Glad to have another data point on a question I am still thinking through, and a look at urbanriders added two more, content that acknowledges its place in a wider conversation rather than pretending to settle the question alone is intellectually honest in a way that I wish was more common across the open web.
Took longer than expected to finish because I kept stopping to think, and a stop at focusoverforce did the same to me, content that provokes thought rather than just delivering information is in a different category and the team here is clearly working at that higher level rather than just cranking out posts.
Solid endorsement from me, the writing earns it, and a look at executeplansnow continues to earn it across the broader site too, the kind of operation that maintains quality across many pages rather than just one viral post is a sign of serious commitment and that is what I see here clearly across what I read.
Thanks for the moderate length, neither so short it skips substance nor so long it bloats, and a stop at focusoverforce hit the same balance, the right length is one of the hardest things to calibrate in blog writing and I appreciate when a team has clearly thought about it rather than defaulting.
Liked the way the post got out of its own way, and a stop at moveideasforwardclean extended that invisible craft, the best writing you barely notice while reading because it is doing its work without drawing attention to itself and this site has clearly mastered that disappearing act across the pieces I have read.
Reading this as part of my evening winding down routine fit perfectly, and a stop at directionsetsspeed extended the wind down nicely, content that calms rather than agitates is what I want at the end of the day and this site provides that calming reading experience reliably which is increasingly rare across the modern web.
Closed three other tabs to focus on this one and never opened them again, and a stop at ideasrequiremovement similarly held attention exclusively, content that crowds out other reading from working memory is content with real density and this site has demonstrated that density across multiple pages I have visited so far this morning.
Reading this brought back the satisfaction I used to get from blogs ten years ago, and a stop at brightlifestyle kept that nostalgic quality alive, sites that capture what was good about an earlier era of internet writing are increasingly precious and this one is doing that without feeling like a deliberate throwback at all.
Saving the link for sure, this one is a keeper, and a look at strategyinplay confirmed I should bookmark the entire site rather than just this page, the consistency across what I have seen so far suggests there is a lot more here worth coming back for soon when I have more time.
More substantial than most of what I find searching for this topic online, and a stop at clarityfuelsaction kept that quality consistent, this is one of those sites where the writing actually rewards careful reading rather than punishing the patient reader with empty filler stretched out across long paragraphs that say very little.
Just one of those reads that left me feeling slightly more capable rather than overwhelmed, and a look at executeplansnow kept that empowering feel going, the difference between content that builds the reader up and content that intimidates them is huge and this site clearly knows which side of that line to stand.
Genuinely well crafted writing, the kind that makes the topic look easier than it actually is, and a look at rapidvoyager added even more depth, you can feel the experience behind every line which is something only writers who have been at this for a while can pull off with this level of grace.
Took the time to read the comments on this post too and they were also worth reading, and a stop at actioncreatesmomentum suggested the community quality matches the content quality, when the conversation around a piece is as good as the piece itself you know you have found a real corner of the internet.
Started taking notes about halfway through because the points were stacking up, and a look at intentionalprogresspath added enough material that my notes file grew further, content that demands note taking from a passive reader is content with substance and the writers here are clearly producing that kind of work consistently across topics.
Quietly building a case in my head for why this site deserves more attention than it currently seems to receive, and a look at motionbeatsmotionless reinforced the case, the gap between quality and recognition is a recurring frustration in independent online content and this site is one of the cases that seems particularly egregious to me today.
A genuinely unexpected highlight of my reading week, and a look at executevisionnow extended that pattern, the surprise of finding excellent content rather than the predictable mediocre is one of the few real pleasures of casual web browsing and this site delivered that surprise cleanly today which I really do appreciate.
A memorable post for me on a topic I had thought I was tired of, and a look at executevisionnow suggested the same site can refresh other tired topics, sites that can revive my interest in subjects I had written off as exhausted are doing rare work and this one is clearly doing that for me today.
Started thinking about my own writing differently after reading, and a look at progresswithintent continued that reflective effect, content that influences how I work rather than just informing what I know is content with the highest kind of impact and this site has triggered some of that reflective influence today on me.
