Tetrahedron UFO Floating Over The Kremlin and The Pentagon

In December of 2009, a Tetrahedron UFO appeared over the Kremlin. That same day a mysterious spiral appeared over Norway. Just over nine years later, another Tetrahedron UFO hovered over the Pentagon for hours. We hear from eyewitnesses and experts who examine the footage of these giant tetrahedrons looming over two of the world’s most secure locations.

In geometry, a tetrahedron, also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.

The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a “triangular pyramid”.

For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere tangent to the tetrahedron’s faces.
