- Instrument The Belgian Wave: The night of 30-31 March 1990: two F-16s, nine interception attempts, six radar lock-ons, and not one pair of eyes on anything, inside a wave of some 2,000 reports. The Night view replays the chase in 3D over the sodium-lit Belgian plain, under a star field computed for that exact night, with the 00:29 wingman lock replayed as the Air Force's own study concluded. The Tape view carries the recorded numbers as recorded: 150 to 970 knots, altitudes from 11,000 ft to below zero, a tenth-of-a-second lock. The Court prices them exactly: 970 kt at low level is supersonic at the ground and owes a kilometres-wide boom carpet nobody heard; the jump is 21.5 g read over 2 s and the cited 40 g at 1.1 s, with that dt an open dial; a 5-tonne craft draws about a gigawatt. The Sky rebuilds the stars over Ramillies hour by hour: Jupiter at magnitude -2.1 sinking west, Sirius flashing colours low, the reported quadrant at the reported pace. The Ledger runs from thirteen gendarmes at Eupen to the 2011 polystyrene confession. Two verdicts at equal size: a lock is not a sighting, and a hoax is not a wave

- Instrument The Osmium Fingerprint: INST-46 closed on one undisputed measurement: a platinum spike in Greenland ice that rose a hundredfold over fourteen years, cause unknown. This sequel tries the remaining suspect with the same rigour the impact got: a crack in the ground in Iceland. The Fissure view builds the whole machine at true scale, one unit per kilometre: the famous curtain of fire is a few hundred metres of base, the convective column above it plays against a 9 km subpolar tropopause, about 500 m³/s of column feed clears it, and the three-week channel to Summit, 1,247 km away, is not a model, because Laki demonstrated it in 1783 and Hekla repeated it in 1991, writing a platinum peak into a snow pit at the exact GISP2 site; the control case, Holuhraun, released eleven megatons of SO₂, never topped 4 km, and delivered nothing. The Mixing Bench runs Sun 2020 as a machine: meteorite and mantle are degenerate in the osmium isotope, both near 0.13, but the chondrite fraction that supplies the osmium must deliver iridium at CI proportions, 250 times the measurement, while volcanic gas condensate takes the osmium alone, and the deepest sample at 0.12 sits below anything a chondrite mixture can reach. The Record draws both published tables to the last row: five horizons in four thousand years where an impact predicts one, the gap between 151 and 155 cm shaded rather than smoothed, the disagreeing same-depth replicates in both papers' tables joined in red, and beneath it Abbott 2021's eight sulfate events (seven of them bipolar), V8 at twice Okmok twenty-five years before the onset, with the platinum spike forty-eight years after it, too late to be anyone's trigger. The File runs 2013 to 2026 in nine cards and two verdicts at equal size: a fingerprint without a culprit, a sheet without a crater. The numbers are sourced, the anchors are re-runnable, and the reading is yours
- Instrument The Avrocar: Every other saucer on this site is a claim about physics nobody has demonstrated. This one is an object you can go and stand next to. Between 1952 and 1961 Canada and the United States spent about ten million dollars on an eighteen-foot aluminium disc, built two, flew both, and parked the survivors in museums. The Rig view is the machine in 3D at true scale with a person beside it, because the question about this aircraft is a distance: the gap between the rim and the ground. Raise it and the cushion dims, the augmentation falls, and past about two feet the disc breaks into the pitch and roll the programme called hubcapping. The Ledger explains the aeroplane in one line. Thin-jet cushion theory makes lift a flat thrust term plus a term in 1/h; anchor it on the two published weights, 3,150 lb with no ground under it and 4,285 lb held at three feet, and the whole aircraft collapses to L(h) = 3,150 + 1,038/h pounds, with the ceiling for any weight at 1,038/(W − 3,150) metres. One constant is fitted and it is the finding: the machine realised 0.24 of the cushion the textbook owed it, next to a turborotor that returned 1.14× from a lift fan that should have doubled its thrust, and the record names the cause as duct losses that were never resolved. The punchline is arithmetic: 3,150 lb of lift against a 3,000 lb empty airframe leaves 150 lb for the pilot, the fuel and the payload together. The Mistake view then tests the file's own 1954 memorandum about circular aircraft being mistaken for UFOs, against angular size (moon-sized at 600 m, not a disc at all beyond 19 km) and against an altitude ladder built from this site's other instruments. The File runs from a 1952 research contract to a museum floor and closes on two verdicts at equal size: it was real and it flew, and it never left the cushion. The numbers are sourced, the assumptions are printed on the machine, and the reading is yours
- Instrument Special Report No. 14: Everyone quotes one percentage from this document, and almost nobody says which of its three counting bases that percentage belongs to. In 1955 the Air Force received a statistical study it had commissioned: about 4,000 reports of unidentified aerial objects from 1947 to 1952, reduced to IBM punched cards and charted as 3,201 sightings. The Sort view lays the six evaluation bins out on all three bases and hands you the denominator rule: under ten equally defensible rules the same file runs from 17.1% to 30.8%, and the famous 21.5% sits near the bottom of that range. There is a trap alongside it, because on the object-sightings basis the cell reading 474 = 21.5% belongs to Aircraft. The Chi Square view turns the report’s own twelve tables into a working machine: six characteristics, the knowns with and without astronomical cases, the report’s statistic against the textbook one, a switch for the ‘not stated’ bucket it never priced, and the exact p values 1955 could not compute. The finding is right there: the analysts honestly tested whether the unknowns were just knowns seen badly, five characteristics of six rejected that at better than 1%, and the report called the result inconclusive and drew its conclusion from somewhere else. The Quality view draws Figure 8 as a mosaic, where 33.3% of excellent reports ending unknown against 16.6% of poor ones is real, and doubtful coming in below poor means the staircase everyone quotes has a step going the wrong way. The File hangs two verdicts at equal size, and both of them are the report’s own
- Instrument The Reflection Bench: CIA-UAP-003 makes two claims in one paragraph. One is a mechanism: at dusk the sun had already set for an airliner while a U-2 far above it was still in sunlight, its silver wings catching the sun and reading as a fiery object. The other is a population: that these aircraft accounted for more than one-half of all UFO reports of the late 1950s and most of the 1960s. The first can be computed exactly and the second has to be counted, and this bench does both. The Sky view is the moment itself over a real 6,371 km Earth, built with three.js's sky shader: run the evening and watch the aircraft at 40,000 ft go dark while the one at 70,000 stays lit. The Geometry view gives the whole reason as one subtraction, a horizon dip of 4.68 degrees at 70,000 ft against 2.51 at 20,000, with the refraction allowance identical at both ends and therefore cancelling, so the width of the window does not depend on the atmosphere at all. The Glint view calibrates its model on a measured Iridium flare before it describes an aircraft, then finds a steady gleam near magnitude -1 and a specular flare near -10, and sweeps the one quantity nobody published, surface roughness, across forty times its range without the conclusion moving. The Count view draws Project Blue Book's whole year table, 1947 to 1969: 12,618 reports, 8,587 inside the claimed window, and 4,294 sightings demanded by more than one-half, against a record whose largest year predates the U-2's first flight by three, whose 1959 was a nine-year low at the programme's height, and only half of whose window falls in years when any of these aircraft was still bare metal. The File closes on two verdicts at equal size: the geometry holds, and the count does not. The numbers are sourced, the assumptions are printed on the instrument, and the reading is yours
31 July 2026
- Instrument Project Daedalus: From 1973 to 1978 thirteen volunteers of the British Interplanetary Society computed the first complete engineering study of a starship: 190 metres, 54,000 tonnes, 250 D/He-3 pellets a second imploded by electron beams and exhausted through a magnetic nozzle at 10,600 km/s, 3.81 years of thrust for 12.2% of light speed, then a 46-year coast to a flyby of Barnard's Star at 5.9 light-years. The Ship view draws the two-stage stack to the report's dimensions with every part clickable; the Pulse view goes inside the chamber with three clock speeds to watch one pellet die; the Voyage view draws fifty years as a draggable rocket-equation curve pinned to the study's milestones, with a braking ledger alongside: 54,000 tonnes to fly past, about 1.7 million to stop, Freitas's REPRO over 10 million; the File view runs from the thirteen volunteers to NIF's one-shot-a-day ignition and Barnard b's 2024 return, closing on two verdict cards at equal size. The numbers are sourced, the curve is arithmetic, and the reading is yours
- Instrument Fata Morgana: The optical mirage, built as a drivable bench. The Strait view is a computed picture, one traced ray per screen row: standard air keeps a ship at 22 km hull-down, and six kelvin of warm air over cold water raise it back as stacked walls and towers, the Fata Morgana proper. The Ray Bench spreads out the T(z) and M(z) profiles, shades the duct where dM/dz goes negative, and prices the +0.11 K/m threshold live from your dials: the same machine as Washington 1952's radar duct, moved to the optical band. The Image Machine collapses the whole phenomenon into one transfer curve, where folds are stacked images and backward runs are inverted ones, with a draggable probe to count them. The File runs from the sun returning two weeks early over Novaya Zemlya in 1597, ray-traced closed in 2003, through the Min Min lights reproduced with parked headlights and the Marfa lights tracking US-67 traffic, to the Condon Report's bounds: within about a degree of the horizon, D = 500 H, a real source required. Two verdict cards at equal size: what the duct delivers, and where the explanation stops. The formulas are textbook, the cases are sourced, and the reading is yours
- Instrument Bolide Reentry: Fireball-versus-craft, built as a drivable bench. The Sky view replays four events from the witness's side: the 1968 Zond IV slow train that letters described as a cigar with lighted windows, Chelyabinsk 2013 at nineteen kilometres per second, the 1972 Earth-grazer that crossed the sky and left, and the 1913 Great Meteor Procession, with an assumed-distance dial showing how one unmeasurable number turns the same track into an airliner or a bolide. The Bench integrates the single-body meteor equations live: altitude against downrange, speed against the two entry bands, the light curve, dynamic pressure against strength, with breakup altitude reading out the material, stone in the forties of kilometres against a rocket stage near 77. Two Worlds sets the ballistic integrator beside a thrust-equipped sketch and lights up six checkable discriminators as the sketch cheats: one-way deceleration, dead-straight tracks, mass-sorted trains, the speed bands, bounded duration, the sound delay. The File runs 1913 to 2021 and closes on two verdict cards at equal size: reentries reliably manufacture craft, and the physics is bounded. The equations are textbook, the cases are sourced, and the reading is yours
- Instrument Project Mogul: Where-did-Flight-4-go, built as a drivable bench. The Map view integrates a 600-foot balloon train's drift through the June 1947 winds over New Mexico, layer by layer: solid where the SCR-584 tracked it, dashed past Arabela where Moore's contested reconstruction takes over, with Flight 5, the tracked-and-recovered control, and the single weather balloon Ramey actually showed the press one click away. The Train view lays the cluster open to scale, 23 neoprene balloons, three foil radar targets, a Navy sonobuoy, beside a live altitude-time profile where sunrise starts the ultraviolet attrition clock. The Debris view sets Brazel's 1947 newspaper inventory against the train's bill of materials line by line: seven lines match, the eighth ('no strings or wire') draws a full-size mismatch, and the post-1978 retellings (memory metal, hieroglyphs, bodies) sit in a separate strip no balloon explains. The File runs from two diary sentences in June 1947 to 1997 and closes on two verdict cards at equal size. The rates are recorded, the quotes are sourced, the winds are tuned and say so, and the reading is yours
- Instrument The Arecibo Message: The 1974 transmission, built as a drivable bench. The Send view replays all 167.9 seconds live: 450 kilowatts at 2380 MHz, ten bits a second, a beam 1.7 arcminutes wide that is a needle rather than a floodlight, the most recent bits riding it in two frequency lanes, a corner waterfall drawing the two narrow columns a receiver would have seen, and a logarithmic journey strip holding the wavefront where it actually is today, about 52 light years out. The Decode view hands you the fold: 1679 factors only as 23 x 73, and that fact is the decoding manual, riding inside the length of the message; set the width to 41 and perfectly intact data shreds into diagonal noise, snap back to 23 and seven sections drop into place with a colour sweep. The Compose view gives you the same 23 x 73 envelope and the same transmitter, lets you paint, and prices the result against distance: readable to about 93 light years, detectable to about 3,100, against an M13 at 25,000. The File runs from a 1961 cryptogram one person on Earth solved to Ryle's objection filed within days, the 2001 Chilbolton formation and the 2020 collapse. The bits are the original, the link budget's five assumptions are printed on the face of the instrument, and the reading is yours
- Instrument Technosignature Spectroscopy: When a planet crosses its star, a sliver of starlight grazes its atmosphere on the way to us, and the molecules there absorb at their own wavelengths. Measure the transit depth against wavelength and you have read the air of another world. The Transit view lays out the geometry the whole science lives in: a star, a planet, and a hair-thin ring of atmosphere that nearly vanishes when you switch the exaggeration off. The Spectrum view is the bench itself, with four worlds, six atmospheres, seventeen molecules and four real JWST modes. Its cross-section ladder is not asserted but solved, by inverting the model against the known effective altitudes of these same bands in Earth's own limb, which puts the halocarbons near 1e-18 square centimetres against oxygen's 7e-26, about seven orders of magnitude apart. The entire model is pinned to a single measurement, WASP-39b's 4.3 micron carbon dioxide feature, and the other checks agree on their own. The Verdict view lays out the five rungs between a bump in a spectrum and a claim about life and computes where each one breaks, including the term that decides it: the star's own spots, measured at 134 to 376 ppm across four real TRAPPIST-1e visits against a planetary signal near 15, and they do not average down with more transits. The File runs from Lovelock in 1965 through Sagan's 1990 control experiment, where the chemistry said life and only the radio said technology, to the eighteen months in which K2-18b's biosignature failed to survive being checked. The assumptions are printed on the instrument, and the reading is yours
- Instrument The Younger Dryas Impact Ledger: In 2007, twenty-six authors proposed in PNAS that an impact 12,900 years ago ended the Clovis culture, killed thirty-five genera of megafauna, and tipped the planet into a twelve-hundred-year cold snap. This instrument does not summarise that argument; it runs it. The Layer view puts seventeen sites on one axis: under the proponents' own Bayesian model fifteen of fifteen touch the claimed boundary and the layer looks synchronous across four continents, while switching to ages measured directly on the layer leaves five of eleven, with Lommel's charcoal five hundred years too old and Gainey, which supplied the highest microspherule count ever published, having its carbon spherules dated to about two centuries ago. The Impactor view computes five requirements that must hold at once, all from Collins/Melosh/Marcus 2005: delivering the measured 82.2 ppt platinum spike takes a kilometre of iron, a kilometre of iron leaves a twenty-kilometre crater, shrinking it until the crater could hide drops the platinum by four orders of magnitude, and growing it until it could burn a continent makes it a once-in-thirteen-million-year event. The fifth cannot be bought at any size, because aerosols clear the stratosphere within fifteen years and the stadial lasted 1,193. The Ledger gives all fifteen lines of evidence: the ones that were not reproduced, the ones that turned out not to be unique, the ones refuted, and the two retracted in February 2026. The platinum spike is real and nobody disputes the measurement, and the paper reporting it says in its own words that no such crater has been found, and its lead author now co-authors the refutation. The numbers are sourced, the arithmetic is auditable, and the reading is yours
- Instrument Exoplanet Direct Imaging: Humanity owns one photograph of an inhabited planet: the 0.12 pixel Voyager 1 caught in a sunbeam in 1990, taken from inside the system. Retaking it from the next star over is a problem with two numbers nailed to it: an Earth twin at 10 parsecs sits 0.1 arcseconds from its star at one ten-billionth of its brightness. This instrument builds the whole route. The System view is the geometry in 3D: a tilted orbit against the coronagraph's ring of blindness on the sky plane, with the projection point diving inside the mask exactly at full phase, where the planet is brightest. The Coronagraph view is the bench: the exact Airy pattern of a flawless 6 m telescope (the first ring alone carries 1.75% of peak), Lyot's 1930 mask, a speckle floor that rides the stability slider at (πh/λ)², where a 2-picometer ripple fakes an Earth, and the dark hole a vacuum testbed has already held at 4e-10; on the far side waits the photon famine, one photon every eight seconds. The Ledger sets everything imaged, 98 self-luminous young giants in the infrared, against everything wanted in reflected light, four orders of magnitude below, with a 164-star neighbourhood ladder deciding which habitable zones even open outside the mask. The File runs from the 0.12 pixel through Roman's August 2026 launch to HWO's ~25 modelled Earths in the 2040s, and keeps Fomalhaut b, the dust cloud that spent twelve years as a planet, on purpose. The numbers are sourced, the assumptions are printed on the instrument, and the reading is yours
30 July 2026
- Instrument Precession & the Orion Correlation: Earth's axis rides a 23.4° cone once every 25,772 years, and the whole sky slides against the horizon on that clock, which nobody can wind back or fake. Bauval's famous claim makes that clock its hinge: the three pyramids of Giza map Orion's Belt as it stood at the trough of 10,450 BC. This instrument builds the clock and lets every party make their case on it. The Sky view is a planetarium at Giza with an epoch dial thirteen millennia deep each way; the Match view sets Petrie's survey against the Belt of any epoch, with Krupp's upside-down objection and Fairall's protractor each wired to a switch; the Clock view draws the axis cone and the trough curve that stays within 15 arcminutes of its bottom for about a thousand years; the Shafts view lets the Great Pyramid's four measured shafts date themselves, clustering at about 2,500 BC. The precession is measured, the claim and the objections are quoted from their sources, and the reading is yours
- Instrument Mantell 1948: The first death in the official UFO record, rebuilt as a physics bench. On the afternoon of 7 January 1948 the Godman tower watched a white object hang to the south-west for over an hour and asked four ferrying F-51s to look; the leader had no oxygen aboard. The Chase view replays the afternoon on the reported timeline: the 15,000-foot transmission, the wingmen breaking off near 22,500, and a consciousness reserve integrated from the published physiology table that runs dry before 25,000 feet, where the accident report put the blackout; the watch stops at 3:18. The Sight view is the angular-size machine the whole case runs on: the tower measured a quarter of the moon, so pick a diameter and read the distance it implies, from the patrol's 300-foot disc to a 70-foot secret Skyhook. The Climb view adds a draggable turn-back altitude for the afternoon he did not fly, and the Record view lays out the statements, the accident report, Venus argued down by its own file, the Skyhook identification with its missing launch record, and the legends. The physiology is measured, the timeline is relayed, and the reading is yours
- Instrument Project Stargate: The U.S. government's 1972-1995 remote-viewing program, rebuilt as a statistics bench. Twenty-three years, about $20 million, six code names, and the entire empirical residue is one sliver: an effect size near 0.2 across the program's own remote viewing, and a 32.2% hit rate from a 1994 ganzfeld series run outside it, where chance earns exactly 25%. The Protocol view takes one trial apart as a machine: the sealed booth, the four-candidate pool, the randomiser, the blind judge, and the claim under test drawn as a dashed question mark. The Chance Machine drops series into a live histogram: watch pure luck build its bell, then lay the autoganzfeld's 32.2% and Utts' effect size 0.2 over it and watch z grow with the square root of N. The Leaky Lab runs a clean and a leaky zero-psi laboratory side by side, with five switches from the published critiques that can drift the coral pile onto the claimed line. The File sets out the 1995 AIR review, where Utts and Hyman read one dataset and signed opposite verdicts. The baseline is arithmetic, the claims are sourced, and the reading is yours
- Instrument Green Fireballs: The 1948-1951 New Mexico green fireball case, rebuilt as a triangulation bench. The Two Falls view replays a conventional meteor and the Starvation Peak fireball over the same desert night: steep, decelerating and loud 45 seconds later, against instant-on, level at 8 to 10 miles at constant speed, two seconds, silent. The Triangulation view is the heart of the case: five AESS posts report azimuth and elevation with error you dial, a least-squares intersection solves the true path, one station gives direction only, two decide a line, and the slope readout settles meteor world or fireball world in a single number. The Colour view sets copper's 510-522 nm against magnesium's 517-518 nm on a real spectrum strip, under LaPaz's naked-eye 5,200 Å and the eye's resolution band: the eye cannot split copper from magnesium, which is exactly why Sandia went looking for powder on the ground. The File view lays out the 1949 Los Alamos conference, where LaPaz and Bradbury left opposite readings in the same minutes. The geometry is arithmetic, the claims are sourced, and the reading is yours
- Instrument The Piri Reis Map: The 1513 Ottoman chart rebuilt as a cartography bench. The Chart view redraws the gazelle-skin fragment with every disputed feature clickable: the Amazon drawn twice, roughly 900 miles of missing coast, the Caribbean drawn to Columbus's cosmography, the southern land annotated with heat and big snakes. The Projection view honestly builds the azimuthal equidistant machine Hapgood claimed, its centre free to stand at Cairo or anywhere: distance and bearing from the centre are exact by construction, and Queen Maud Land falls 11,400 km out in a smeared arc that quarrels with the snug coast the parchment draws against South America. The Southern Land view hands the coast to least squares with three candidates fitted live, subglacial bedrock, the modern ice edge and a Patagonia bent east, RMS printed, the Drake Passage's 800 km gap drawn alongside. The File view lays out 1513 to 2000: Mallery's broadcast, the Ohlmeyer letter, and the Hapgood and McIntosh verdict cards at equal size. The geometry is arithmetic, the claims are sourced, and the reading is yours
29 July 2026
- Instrument The Casimir Effect: Two uncharged metal mirrors in vacuum, pushed together by the vacuum itself: fewer electromagnetic modes fit between them than outside, and the gradient of that deficit is a force measured to better than 1%. The Gap view thins the standing waves out one by one as you tighten the separation, force arrows growing by the exact fourth-power law; the Modes view draws the 1948 counting argument as an honest cartoon; the Curve view lays the measured law over the four real campaigns, Sparnaay's ±100%, Lamoreaux's 5%, Mohideen's 1%, Decca's sub-1%, with the unresolved Drude/plasma thermal dispute as a switch; the Ledger prices the gap's negative energy against INST-12's warp bill on a log ladder: about sixty orders short, with the Ford-Roman inequalities rationing even that. The force is measured; the negative energy is an inference; what it proves about the vacuum is yours to read
- Instrument ECM Phantom Targets: For a radar to see a target it pays a round trip, so the echo falls as 1/R⁴. A jammer riding that target pays one leg and falls as 1/R², and that single difference of exponent is the whole of electronic attack. The Engagement view holds one real aircraft and strings the radar's belief beside it as phantom copies; the Scope view is a B-scope with real phosphor persistence, where you watch a tracking gate get captured, walked off the aircraft and dumped empty, then click two blips for the speed a vehicle would have needed when nothing accelerated at all; the Duel view draws the echo, the jammer and the noise floor on one chart, with burn-through where the radar wins the argument back; the Debrief maps the released Range Fouler record against what this bench can and cannot make, including the noise jamming logged in D58 and the negative ES recorded in D56. The techniques are documented engineering, and the boundary is stated just as loudly: electronic attack writes to a receiver, not to an infrared sensor or a human eye

- Instrument Electrogravitics: Charge an asymmetric capacitor to tens of kilovolts and it moves toward its positive side. Nobody disputes that; the dispute is why. The sceptic says ion wind: charged air thrown backward, useless in space. Thomas Townsend Brown, and the 2008 book built on him, say charge couples to gravity. This instrument computes both readings from the same dials and hands you the decisive one: pump the chamber from one atmosphere down past a billionth of one, where ions cannot exist. The Bench flies Brown's 1950 tethered discs; the Jar rebuilds the Paris vacuum chamber and the discharge that spun the rotor until they feared it would shatter the bell jar; the Craft stages the seventy-foot aero-marine proposal of 1960 that was never built; the Curve lays out the Navy's 1952 data; the Ledger prices both readings row by row, with the author's own chapter 12 nulls as the counter-bill. Every constant in the electrogravitic branch is the book's own. One arithmetic error is corrected on screen

- Instrument Quantum Eraser: Tag which slit a photon took and the double-slit fringes die, no one has to look. Erase the tag and they only come back once you sort the hits by the eraser's two channels: one a fringe, the other its exact anti-fringe, while the combined screen stays flat. Even when the choice is made after the photon has landed. Step through the three configurations, flip the view from the combined screen to the sorted channels, and switch the marker and 45-degree analyser yourself. No retrocausation here: no signal travels back, only a correlation is revealed
