Those who don't believe in UFOs certainly have some valid points, for instance: If there are UFOs, where is the physical proof? True, this proof is hard to come by. There are however, a few fairly good examples of what may constitute that proof. Ibrahim Sued, a columnist for the Rio de Janeiro newspaper "0 Globo" received an odd letter one day. This letter described the explosion of a flying disc at a Ubatuba, Sao Paulo, Brazil, beach. Sued published the letter on September 14, 1957, which alluded to three small pieces of metal which came in the letter.
"Rained Down" from Exploding Disc:
The letter explained how this metal had "rained down" from a flying disc, and some of the metal had been collected by the sender of the letter. The return address could not be deciphered, and there was no reference to any witnesses of the explosion. Dr. Olavo Fontes, representing Brazil's APRO, launched an all out search for more information on the explosion, but found nothing.
Two Separate Incidents:
What little information that was included in the letter was just not sufficient enough to track down any leads. Sued was told that the explosion was over Toninha Beach in 1957, which narrowed down the search. A piece of metal from the Toninha incident was analyzed and showed a 99.99% pure magnesium. One of the other fragments supposedly came from one of the three UFOs that were seen flying over Caminas, also in Sao Paulo, in December 1954. This fragment was 88.91% tin alloy.
Analysis of Fragments:
Finally, Sued surrendered all of the metal to Dr. Fontes, who had arranged for the finances to have them analyzed at the Mineral Production Laboratory of the Department of Mineral Production in the Brazilian Ministry of Agriculture. For security purposes, Fontes hand delivered the samples. Internationally known chemist Dr. Fiegl performed a qualitative, acid test, which proved that the samples were magnetic.
Pure Magnesium:
Dr. Fontes took one of the first fragments, and had it subdivided into several smaller pieces, and sent two of them to the Spectrographic section of the Mineral Production Laboratory Semi-Quantitative Emission Spectrochemical Analysis Lab. Another of the pieces was analyzed by Dr. Luisa A. Barbosa, whose results showed that the metal was made up of only the element magnesium.
