This U.S. Department of War file collects Project Sign era checklists and incident summary sheets for incidents 101 to 172. The largest item is the 18 February 1948 explosion over Norcatur, Kansas. For it the file gathers witness statements, speculative letters from Norman G. Markham, and Dr. Lincoln LaPaz's view that it was a genuine meteorite fall with curious aspects. Other entries cover B-29 crews, a two-decked wingless object over the Netherlands, a Turkish rocket report, a Moscow sighting, and George Gorman's 1 October 1948 Fargo encounter.

I submit there is a likelihood that on June 24,1947,something like a space-ship came here from the moon and upon February 18,1948,returned to the moon. This is of course speculation. But has anyone yet explained the "flying discs" in terms of all the pretty-well proven facts in connection with them? Has anyone yet devised a fuel powerful enough to kick a rocket from Earth to the Moon? There have been hundreds of reports, during the past century, on occurrences which imply this world is visited from outside space. Absence of contact by these postulatable visiting entities may imply a state of culture far beyond ours, to the point where it would be inexpedient for their members to have to do with us en-masse. These reports have never been seriously considered by science, which in general ignores them. However, according to Dr. Rocht of Chamberlin Observatory, Denver, there is nothing in astronomy to explain the thing which exploded over Norcatur. Dr. Nininger's idea that the thing was a meteor flatly disregards Dr. Rocht's opinion, which may have been based on the Denver Posts' statement that a Denver woman saw the Norcatur object twenty minutes before the explosion occurred. I submit that the Army needs men who are capable of recognizing the anomalies beforementioned when they occur, evenif only to aid in speculation regarding them. The undersigned offers his services to that end, if the Army may wish to avail itself of them.
