Further to the commentary on official situation around the time of Rogue River. The situation at WPAFB and Pentagon are still somewhat fluid on UFOs at this time. Policy and discipline have not been set in stone yet. I wrote on this on the Project 1947 site
This commentary is sadly out of date.
First. despite what Ruppelt says about AF Intel as the origin of Shallet's article, that was not the case. In fact Cabell fought against it. Shallet's involvement comes from Mr. Leo and General Vandenberg (and possibly Forrestal) as Shallet apparently was in good with all three. Checking Vendenberg's papers at the Library of Congress shows that there were regular meetings among Shallet, Vandenberg and Mr. Leo from an early date. Shallet was doing a whole series of articles for them on topics the AF wanted before the public. The Shallet UFO article was planned earlier but put on the back burner until other things were done. Gen Van does have one meeting with Shallet in UFO were apparently the only topic discussed. When the subject becomes the leader in the quell of items, several other things are coming together, the Project Saucer Report, deemphesis of UFO project, Cabell's insistence that AF Intel be the source of public UFO info (he obviously lost this battle to Mr. Leo), etc.
Shallet's article comes out about the same time that the Project Saucer press release hits the wires, but at the same time someone (I suspect Loedding as he would feed the press stories from time to time under an assumed name) went to the Dayton papers adding a more positive spin and revealing more details about the Mantell case which were not public nor in the Project Saucer news release. The Dayton newspapers put this story on the wires. The rather long Project Saucer news release was not negative against UFOs and recounted various UFO incidents. Editors and reporters could then boiling it down could emphesize positives or negatives depending on their personal points of view.
When compared to the later Project Grudge releases the Project Saucer release was quite moderate and objective. The saucers go from being "no joke" in the Project Saucer release to completely explained and not worhy of much effort. The two news stories, Project Saucer release and the Dayton interview collided (for what of a better word to illustrate what happened) and were amalgamated together in various forms, some which were negative and some which were very positive depending on the newspaper and rewites. Again, the Project Saucer news release had the theme that the AF was on top of the problem and UFOs seemed not to be anything of import, the door was left open unlike Shallet's articles.
Finally a few days later the Air Force Times did a story datelined from WPAFB which again sounded very positive towards UFOs and investigations.
This would not happen again, the two Project Grudge releases in August and December 1949 were short, to the point, and negative. There was no question where the AF stood, and there was not other opinions leaking out from other sources.
Now to Project Grudge itself:
1. Early on there seemed to be some type of idea that interesting cases should be more thoroughly analyzed, the Southern Oregon navy pilot case in which he saw the UFOs against the mountains and the CB Moore case.
2. The investigators and intelligence officers in the field were uncertain about how much effort to put into investigations. One Army memo acknowledging the receipts of case investigations from intelligence officers advises that not much effort should be put into investigating such cases.
3. All directives on UFO investigations are superceded and field organizations are told to report through regular channels.
In this still fluid situation comes the Rogue River report. Some at TID might take it seriously, but they do so at their professional peril.
Cabell must take some responsibility for this situation. First he de-emphesizes UFOs, reduces effort at WPAFB, then he tells them to close Grudge, then later he tells WPAFB to reopen the investigations with more emphesis. This lack of clarity is what Watson complains about in his April 1950 memo to Cabell. Watson wants firm guidance not wishy-washy policies when contrasted against what the AF is putting out to the public.
One last point:
Exactly what Major Boggs position in HQ AF intel in relaions to UFOs was in somewhat unclear, but he seem to be the point of contact (POC) on UFOs. If so, he is most negative about UFO although he does talk about how to get more info in one Top Secret memo. Since he is he POC, he influences the internal AF attitudes toward UFOs. I think one should pay attention to Lt. Col Rosengarten's quote about the "saucer boys." The AF was interested in unidentified flying objects, not flying saucers.
