UFO Physical Evidence

Introduction

There are a variety of items of physical evidence which have been attributed to UFOs. This section attempts to collect information on the scientifically examined subset of that evidence for access by researchers.

Ground Traces

• An analysis of the 1981 Trans-en-Provence trace case to determine the physical parameters of the object and the point in the sequence of events where the trace was produced - a surface trace left behind by a small UFO in 1981 was analysed in depth by a department of the French Government. This paper takes that analysis one step further in an attempt to understand the mechanism and timing of its formation.

Metallic Samples

• The Ubtatuba Magnesium - several fragments of ultra-pure magnesium were attributed to the destruction of a UFO over the near-shore ocean in the vicinity of Ubatuba, Sao Paulo, Brazil in 1957. This paper, written by Olavo T. Fontes in the early 1960s, is of great historical interest.

• Tungsten Carbide from near Vaddo, Sweden - a geometric piece of tungsten carbide was found after a close encounter in 1956.
