Frozen just preceded me in preparing the document. Nice timing

Anyway what I can add about this document and other two that carries Grudge Project name is what the Project Grudge it self is all about. Most of us know very well when it started and it dealt with but for the newbies and member who are not familiar with this name let me quote something from Wikipedia:

Project Grudge was a short-lived project by the U.S. Air Force to investigate unidentified flying objects (UFOs). Grudge succeeded Project Sign in February, 1949, and was then followed by Project Blue Book. The project formally ended in December 1949, but actually continued on in a very minimal capacity until late 1951.

Project Grudge was formed when Project Sign was decommissioned officially on February 11, 1949. The name was about all that would change. Project Sign's final report was classified "Secret." At this time in history, there were a number of Air Force investigators who accepted the possibility of extraterrestrial intelligence. How else were these unexplainable objects getting to Earth from distant planets? These were considered the "dreamers;" those who had vision, and could accept facts without seeing actual physical proof. Another group of disbelievers had no vision or imagination. They would only accept the possibility that UFOs were real when they saw a saucer land on the White House lawn.

One small change from Sign to Grudge was the desire to actually explain or put a tag on every single report; not only a difficult task but totally without precedent. This would look good in a report, yet offer no new scientific theory as to what UFOs were.

One item of interest to the student of UFOs would be an article written by Sidney Shalett of the Saturday Evening Post about the Government's research into UFOs. At the time, the name Project Grudge was not known to the public, and Shalett used the name "Project Saucer" instead. It has been said that Shalett penned the first public use of the term "UFO" in his article of April 30, 1949.

Grudge would fair no better than its predecessors, and closed down after about eight months. They issued a final report also, containing 273 UFO sighting reports. A whopping 23% of these were listed as "unidentified."

Little was done for a time, until on September 11, 1951. A last gasp effort was organized by Captain Edward J. Ruppelt, who took over as head of Grudge. Shortly a month later, a new short lived effort was begun. Usually tagged Grudge II, about all that was new was office forms. The Battelle Memorial Institute, actually a think tank, was asked by the Government to take over the job of explaining UFO reports. They were to review all reports to date. In March of 1952, enter Project Blue Book, which would be the official UFO study group for the United States. Blue Book lasted until 1969.
