It was four years ago that journalist Leslie Kean brought a lawsuit against NASA to uncover documents from the Kecksburg 1965 UFO incident, in the aftermath of production of a Sci Fi Channel documentary, “The New Roswell: Kecksburg Exposed.” The documentary has since been posted online and you can watch it here. Now, after the four-year court battle:

NASA has agreed to search its archives once again for documents on a 1965 UFO incident in Pennsylvania, a step the space agency fought in federal court. The government has refused to open its files about what, if anything, moved across the sky and crashed in the woods near Kecksburg, Pa., 40 miles southeast of Pittsburgh.

Traffic was tied up in the area as curiosity seekers drove to the area, only to be kept away from the crash site by soldiers.

The Air Force’s explanation for the unidentified flying object: a meteor or meteors.

“They could not find anything,” one Air Force memo stated after a late-night search on Dec. 9, 1965. Several NASA employees also were reported to have been at the scene.

Eyewitnesses said a flatbed truck drove away a large object shaped like an acorn and about the size of a Volkswagen bus. A mock-up based on the descriptions of local residents sits behind the Kecksburg Volunteer Fire Department.

UFO enthusiasts refused to let the matter die and journalist Leslie Kean of New York City sued NASA four years ago for information.

“This is about the public’s right to know,” Kean said. “We would be doing this lawsuit regardless of whether UFO groups were interested in it or not. It’s a freedom of information issue.”

Here is the documentary, “The New Roswell: Kecksburg Exposed,” narrated by Bryant Gumbel.
