Disc / saucerCircular or flattened objects described as discs, saucers or lenticular forms.
The HANGAR
A catalogue of shapes and forms described in UAP reports.
Morphology in the reported record
HANGAR groups reports by apparent shape. The categories describe what a witness or sensor record appeared to show; they do not identify an object, establish its origin or imply that similar outlines share a cause.
Each category links the morphology to relevant UAPRAD cases, public records, witness accounts and external sources. A case may appear under more than one form when the original description is ambiguous or changed across the surviving record.
Disc / saucerCircular or flattened objects described as discs, saucers or lenticular forms.
Sphere / orbSpherical objects and unresolved lights whose apparent boundary is circular.
Oval / eggRounded forms described as oval, ovoid, egg-shaped or acorn-like.Deep dive under development
Capsule / ‘Tic Tac’Smooth, rounded and apparently wingless oblong forms associated with modern aviator reports.Deep dive under development
Cigar / cylinderElongated forms described as cylinders, cigars, fuselages or torpedoes.
TriangleTriangular bodies or arrangements of lights interpreted as a single triangular object.
Boomerang / chevronSwept, crescent, V-shaped or chevron forms, including formations perceived as one object.Deep dive under development
Diamond / angularDiamond, lozenge and sharply angular forms that do not fit the disc or triangle families.Deep dive under development
PyramidApparent three-dimensional pyramids and triangular light forms recorded through optical systems.Deep dive under development
RectangularRectangular, oblong or block-like forms reported without a conventional aircraft profile.Deep dive under development
Cube within a sphereA compound form associated principally with modern United States naval aviator testimony.Deep dive under development
Ring / torusAnnular forms and luminous rings whose centre appears open or less bright.Deep dive under development
Cross / cruciformCross-shaped silhouettes or arrangements whose arms suggest a cruciform structure.Deep dive under development
Dumbbell / compoundPaired or multi-lobed forms apparently joined into a single structure.Deep dive under development
Irregular / shape-changingAsymmetrical, changing or poorly resolved forms that resist a stable geometric description.Deep dive under development
