We have all seen the movie starring Will Smith and Tommy Lee Jones, the Men In Black, Secret Agents entrusted with keeping the world safe from Aliens, to trace and track all Aliens who visit the earth.

But what is the secret and mystery behind the movie - is there any truth to the movie? This is the story of the secret government agency - The Men in Black!

The first known encounter with two 'Men in Black' happened in 1947. Two US harbour patrolmen, Harold A. Dhal and Fred L. Crisman, had spotted a UFO over the water of Puget Sound, Washington. Dhalf said that a man dressed in black visited him shortly after the sighting and forcefully advised him not to discuss the incident further.

A similar meeting happened to Carlo Rossi, from the area nea San Pietro a Vico in Italy. In the early hours of 25th July 1952, Rossie was fishing in the River Serchio when he witnessed a strange circular craft hovering over the river. Rossi hid, watching the craft as it passed over him, and then sped away.

In the following weeks he told no-one about what he had seen, but on 15th September he found a stranger dressed in a dark blue suit waiting for him by the river. The stranger spoke Italian, but with an odd Scandinavian accent, and had very strange facial features. The man forcefully asked Rossie about what he had seen, but Rossi denied everything.

A bizarre Men in Black case happened on 18th May 1968, when UFO witnesses started contacting researchers. George Smyth was one of those who had seen a strange object in the skies above Elizabeth, New Jersey, USA.

He began to receive visits from strange men, and received phone calls warning him not to attend upcoming UFO conventions or speak to independent investigators. A bizzare aspect of this case was that the three visitors Smyth descrived were apparently the men he had been told to avoid - the UFO enthusiasts John Keel, Gary Barker and James Moseley.

What made this even more odd was that these three men were actually miles away from Smyth's house at the time of the visits.

Other UFO investigators in the area, John Robinson and his wife Mary, also noticed strange things happening to them. A large dark seemed to be parked outside their house in New Jersey City, with a strange man inside constantly watching them.

One day Mary went out and notice their friend James Moseley making a spectacle of himself further up the street. She thought this was very strange, but went inside to make a drink for him, thinking he was there to visit them. But then the phone rang. To her surprise it was Moseley, not on a street corner in New Jersey City, but rather at his home in Manhattan.
