Scientific Study of Unidentified Flying Objects (the Condon Report, complete, three volumes)

to provt' that it was or wns not a picce of torrodeu metal can, for
project investigators S be an alloy of magnesium, aluminum, and zinc, The other sample,
weighing several grams, was an iron--chromiuffi_-manganese alloy in
unworked, crystalline state. Large cryst.als extending from one surface
suggested th:s sample had solidified at the edge of a vessel from which
ti,e rest of the melt had been poured. Bolh of these materials could
be produced by conventional technology. Proof that they are residue
from a strange object would require demonstratioll that they were
actually found at the site; that they were not there prior to the reported
UFO event and could not have heen hrought there by the automobile or by
othel" means subsequent to the event; that there was dependable c[Jntinui ty
of custody of samples between dIscovery and analysis; and that there
was, indeed, an UFO involved in the reported event. Tn other words, the
existence of these materials, since they are eaSIly producible by
earthly technology, can not serve as evidence that a strange flying
o~ject collided with the automobile in questi0n,
One case described at great length in uro literature (Lorenzen, 1~)62)
emphasizes metal fragments that purportedly fell. to earth at lJbatuba,
Sao Paulo, Brazil from an explodi~g extra-terrestrIal vehicle. The
metal was alleged to be of such extreme purity that it could not havc
heen produced by earthly technolog'(, For that r0'150n, this particular
material has bl~(,11 widely accla1med as a fragment of an clCplodNl flying disc.
DescripUons of the material's origin and analyses occupy 4(, :.1agcs of the
Lorenzen book and the material is rcferreJ to in a high percentage of
UFO writings. 'I1wse fragments of magnesium metal -- undoubtedly the
