Found this interesting post on ATS:
An object that was recovered by Bob White following a UFO encounter in Colorado in 1985. In 1996, White was flown to LANL, the classified Los Alamos National Labs for an analysis of his evidence and was told by Senior staff that the object he recovered was extraterrestrial. The lab denied this later. The Los Alamos official analysis was published for the first time in White's book UFO Hard Evidence (Galde Press 2005). He insists that the results reveal ‘inept or intentionally misleading scientific results’.

However, he is the only man known to have purportedly recovered physical evidence from a UFO encounter. Here’s the piece.…

In 2000, White claimed that a declassified U.S. Army document from the 1940's titled "UFOs in Denmark" has multiple images of an object nearly identical to the one he recovered some 40 years later.

A US ARMY CIC Documents from the 1940's describes an object amazingly similar to Bob White's in File 202085 "Flying Saucers in Denmark". A Freedom of Information Act release of all US Army documents related to UFO's reveals startling information that may support Bob White's claims. Tests performed by MIT research associate Robert Golka and Larry Cekander, Lead Projects Coordinator at Museum of the Unexplained have created an intense interest with members of the scientific community to look at the Bob White Object with a more in depth study that wasn't forth coming before the Neutron Bubble Chamber tests done in November of 2006 in San Diego.

Neutron Radiation should not be present in the object. The radiation exists. Many other things present in the metal shouldn’t be there either but the Thermal Neutron test is a definitive finding of off earth origins. "I believe Bob White has the real hard evidence of extraterrestrial visitation,"says Franklin Carter, president of the Institute for UFO Research.
Scientist think some other academics who have examined the object might have deliberately tried to cover up the truth about it's alien origins.

The Los Alamos report concluded the object was not a meteor but an unknown object of unknown origin.

It seems the military have an ongoing concern about crop circles as seen by their continued interest during the 2007 crop circles season:
Helicopter lands on crop circle -(Poster comment: We were in Eastfield while these Helicopters tried to land into the OM formation.. in the video it is flying away .. near ground..)

Helicopters and the 2007 crop season

Intimidation: (poster comments - Myself and my husband went to Knapp hill in Wiltshire, UK to film mars when it was it's closest to earth a few years ago. We noticed the military were flying around in the distance. We were the only car on the hill when he suddenly turned and came straight for us. It terrified me. I filmed them fly just feet above our car:)

Although this is a bit off the topic about ufos but it is still interesting. Jamie Maussan reviews the alien footage in caught in mexico on a guys mobile phone. I remember watching the video ages ago and thought it was a fake and it was classed as prank by the mexican media - but now Jamie says this is untrue according to new scientific evidence including high radiation at the site.

Original video

"The nations of the world will have to unite, for the next war will be an interplanetary war. The nations of the earth must someday make a common front against attack by people from other planets"
-spoken on October 8 1955. Five Star General Douglas MacArther, West Point Graduate.

Another video form the 1942 event ufo event over LA:

Here are two distinct Flying Saucers filmed separately, By separate individuals. The top filmed in Tallahassee Florida on Sept 5, 2005; the bottom in Deline N.W.T. on Nov 2, 2007. There is no doubt about the authenticity of these videos.

This video was filmed on Nov 2 2007 in Deline N.W.T. The Image was centered zoomed stabilzed

Weird bright, moving Light over central Florida 12/11/2007

Comments from replies to this post : "Something happened over Nova Scotia or the eastern seaboard the evening of Dec. 10-07. First reports were that a spy
satellite/booster launched by NASA failed and burnt up upon re-
entry into the atmosphere. The fact that it launched into a
northerly direction supports the spy-satellite scenario.
The Rescue Co-Ordination Center [RCC] in Halifax first confirmed
this report then recinded it. I learned that they first thought
the rocket had completely failed but then changed that to just
the booster burning up as it came back in. They received many
calls about glowing stuff in the sky, flares and burning type
debris as far west as Ontario with a photo of the thing."
