Smithsonian Associated Museum displaying Item from the 1986 alleged UFO crash in Russia

A Smithsonian-associated museum is displaying an item it says is an 'authentic alien artifact' from a 1986 alleged UFO crash in Russia.

The National Atomic Testing Museum in Las Vegas unveiled an exhibit titled Area 51: Myth or Reality, which presents historical records of the U.S. military site that has long been called the most secret place on Earth.

Among the items is a series of small bits of debris from an incident known as the Russian Roswell.

A clear glass case displays glassy spheres that are debris from a red sphere that streaked over the Russian mining town of bits of metal in vials that streaked over the town of Dalnegorsk and crashed into Mount Izvestkovayaon January 29 1986.

The exhibits description of the debris reads: 'Three Soviet academic centers and 11 research institutes analyzed the objects from this UFO crash. The distance between atoms is different from ordinary iron. Radar cannot be reflected from the material.'

'Elements in the material may disappear and new ones appear after heating. One piece disappeared completely in front of four witnesses. The core of the material is composed of a substance with anti-gravitational properties.'

The debris was given to Las Vegas TV reporter George Knapp, who was the first American to visit the Russian crash site in 1990. Read More
