MynameisJean-PierrePetit.Iwasbornin1937.Atthetimeofthiswriting,Iamover82yearsold.ThroughthisdocumentandtheaccompanyingvideoIsimplywanttotransmitideastopeoplewhomayfindthemuseful.IwouldliketopointoutthatIcannotanddonotwanttomonitoranyprojectsthatmayarise.Myonlypurposeistopointouttheirfeasibility.

In2007,attherequestofsomeyoungpeople,Iagreedtocreateanassociationtowhichthenamewasgiven

http://www.ufo-science.com

ImyselfhavefinancedtheactivitiesofthisassociationtotheleveloftensofthousandsofdollarsthroughthesaleofbooksthatIhavewrittenandpublished.Withthismoneyitwaspossibletofinancesomeactivities.AsaspecialistinMHD(magnetohydrodynamics)at the international level, Ihavedirected themountingofexperimentson low-densityplasmas which have led to results that have been presented in major internationalconferencesandhaveresultedinpublicationsinreferee-controlledjournals(thePolishjournalActaPhysica1).IalsobelievethatIamtheonlyonetohaverelatedmyworkinMHDtotheUFOsubject.Withoutgoingintodetail,thesestudiesfocusedontheoreticalwork showing that it was possible for a flying machine to operate in dense air atsupersonic,andevenhypersonic,speed,withoutcreatingshockwavesorturbulence,i.e.withoutnoise,behaviourimmediatelyrelatedtotheapparentperformanceofUFOs.

Ithasnotbeenpossible,despitealltheeffortsIhavemadeformorethantenyears,from1976to1986,tosetupexperimentalresearch,tomakethisideaareality.Butwehaveseen that the Russians, who know and appreciate my long-standing work, havesuccessfully implemented this technique (see the testimonyofPresidentPutin,duringhis speech given in the Duma2). It has led to military applications such as: the1ActaPhysicaPolonica2012Vol.121n°3;J.P.PetitandJ.C.Doré:WallconfinementtechniquebyMagneticGradientInversions2https://www.youtube.com/watch?v=gSuv0CzSntshttps://www.youtube.com/watch?v=Jn8b3E9oUHY&list=PLfdj8oy5zeoHB8cqu7pJxKLlO4n-bTOJO

implementation of missiles capable of flying at hyeprsonic speed in dense air,hypersonic gliders with high manoeuvrability, and submarine drones at high speed.Techniques directly inspired by the behaviour of UFOs during intra-atmosphericevolutions.

In1986Ishiftedtohigh-leveltheoreticalstudies,touchingoncosmology.Apresentationofsuchworkcanbe found in the Janusvideos3.Thiswork is intendedtodemonstratethefeasibilityofinterstellartravel.

WhetherthroughMHDorcosmology,Ibelievemyworkhasbeenauniqueexampleofahigh-level scientistwhohasdevotedsomuch timeandeffort to thisproposition. Iamconvinced thisworkhas showna clearmeansof confirming theUFOphenomenon asvisits by extraterrestrial civilizations, which has resulted in a dozen or so scientificpublications published in top-level journals, controlled by the peer reviewed journalsystem.

Since2007, theactivitiesof theUFO-scienceassociation, inaddition toallowingmetofinancemyparticipationininternationalconferences,hasbeenanopportunitytotrytodevelop techniquesaimedat capturing scientifically exploitable informationabout theUFOphenomenon.

Tworemarksareinorder.

Unfortunately,examiningthehundredsofthousandsoftestimoniesdoesnotbringmuchthat a scientist can exploit. These testimonies generally seem to be exotic andincomprehensibletoourlevelofunderstanding.

Nor canwe hope to getmuch out of photographs and films due to the fact thatwithtoday'stechniquesitisextremelyeasytocreatefakes.

Inthisdocumentwewillpresenttwoapproaches,bothconcreteandinsimpletechnicalterms, which could make it possible to extract data from the exploitation of opticalinformation. And, in passing, to demonstrate, the apparent exotic nature of thesemanifestations.

The first technique isbasedona technique thatwas implementedby theAirForceasearly as 1952, and aims to obtain a spectrum during a night observation of the UFOphenomenon.Forthegeneralpublic,letusrecalltheprinciplesofspectroscopy.

However, different atomsdonot emit light in a continuous spectrum.Light emissionsarecarriedoutatcertainspecificfrequencies,resultinginaspectrumoflines.Belowisthe emission spectrum of a body that would emit light at three frequencies, thusproducingthroughaslotaspectrumconsistingofthreelines.

Itisnotknownwhattypeoflightisemittedbytheufos.Spectrumcapturecouldprovideinformationonthespectrumandthephenomenonthatgivesrisetoit.ButitispossiblethatthislightemissioncouldinvolveatomsnotpresentintheEarth'satmosphere,suchas lithium. Detecting lines in such a spectrum that betray the action of bodies notpresent in the Earth's atmosphere could demonstrate that the phenomenon thusrecordedcannotberelegatedtoanaturalupper-airphenomenon.

Wepresentedthefirstdevicethat,historically,hasmadeitpossibletoobtainaspectraldecomposition of light. But very quickly, scientists opted for something simpler andespecially lesscumbersome,whichare lineardiffractiongratings.Wewillnotdescribethemechanismsthatcauselighttodecomposeintoaspectrum(actuallytwo,locatedoneithersideofthesourceimage).Thediagramisasfollows:

This helps to understand how a difference can be made between different possiblesources,forexampleofthespectrum.

A second project, which I asked Ufo-science to develop, was that of an automaticsurveillance camera, equippedwith a fisheye lens, capable of operating in a network.Themaininterestliesinthefactthatifseveralcameras(atleasttwo)recordasignal,theanalysisof the imagesnotonlymakes itpossible toreconstruct thethree-dimensionaltrajectoryof thesource,butalso toaccess information tocalculate its speed.We thenobtainasecondmuchmoreinterestingdevicethatpotentiallyallowsustodemonstratethephysicalrealityofufos.

Once again Jean-Christophe Doré has proved remarkably effective in creating a verycheap prototype camera. I am always admiring the qualities of the technicians,whenthey know how to extract the essence of a raw idea and convert it into the simplestpossibleobject.

The object is built around a small fish eye surveillance camera, housed under a glassdomethatisnothingmorethanafragmentofanurbanstreetlampbulb.Therestofthecomponentscomefromplumbing,makingtheobjectremarkablyeasyandinexpensiveto manufacture for a do-it-yourselfer who manages to get his various components.Below isaphotoof thisdevice,which Jean-ChristopheDorécalled"UFO-catch"andofwhichhehastenedonceagaintoregisterthenameandtheplan,always"inthenameoftheassociation".

All this is very interesting, conceptually. The problem is that to have any chance ofcapturingaUFOtrajectory,youwouldneedaverylargenumberofstations.Thistypeofmotorizedstationremainsinprototypestate.

But the FRIPON network is designed so that the data collected by the stations aresystematically sent to a control centre. However, the value of such a system formeteoriterecoveryisnil.Forthisrecoverytobepossible, itwouldbenecessarytosetupthisnetworkina...desert,tohaveachancetorecoverimagesoftheseobjects.

TheUFO-scienceassociation,limitedtoasingle"worker"(inthiscaseJ.C.Doré),cannot,despite his great technical knowledge (he is in charge ofmaintenance in a computerscienceschoolinthecityofRochefort)gobeyondthestageofahobby.In2017,Ihopedthat the concepts developed and perfected by the association, i. e. de facto by Jean-ChristopheDoréalone,couldberelocatedelsewherethaninFrance,particularlyintheUnitedStates.Whentheopportunityarosetosell(for300dollars)astationtoapersonwhowastogototheUSAandwhowaslikelytomeetinterestedgroups,IimmediatelyaskedDorétocomplywiththisrequest.Butherefused.

I therefore considered that, no longer having the slightest authority within thisassociation, I could no longer continue to financewithmy books the activities of theassociation,i.e.thoseof...Jean-ChristopheDoré.IthereforesubmittedmyresignationasPresident at the end of 2017. I naively thought that my letter of resignation wouldconstituteawarning shot thatwouldputa stop to theabuses Ihadobserved.At thattime,theassociationhadonlythreeothermembersbesidesmyself:

I asked Jean-Christophe Doré on that occasion to find outwhat I was leaving behindwhenIleft:
