Estimate of the Situation
In or around August 1948, Project Sign staff allegedly prepared an “Estimate of the Situation” that allegedly reached the conclusion that flying saucers were real and came from outer space.

The alleged existence of this document is controversial, as are details such as its alleged date. It is sometimes stated to have been dated 5 August 1948, sometimes the 1 August 1948, usually simply August 1948, sometimes September 1948, occasionally October 1948 and even “in early 1949”.

Web Resources

There is a rapid turnover of UFO material on the Internet. Many links to material on UFO websites quickly become out of date. Therefore, instead of giving many links to specific webpages I have instead included below a search box which can be used to search various leading UFO websites at the same time. You can then click on tabs at the top of the search results to list only results from forums, only results from websites I have labelled as "skeptical" etc. I have included tabs for a couple of specific websites that I find particularly useful, including the valuable archives of the UFO UpDates email discussion List. The relevant websites are all listed in the discussion of the "UFO Searchillion" search engine in Section 2.4 of the "Free UFO Researcher Starter Pack" and continues to evolve...

 

The relevant search box is one of the two main tools on this website which are intended to help reduce the amount of reinvention of the wheel within UFOlogy. The other main tool is the collection of tables of references to discussion of UFO incidents, personalities and other matters in various books. Those tables can be sorted by author, length and date. I hope these tools are useful.

 

 

 

Book References

The table below includes references to relevant discussions in UFO/SETI books noted by Isaac Koi during a review of approximately 963 UFO/SETI books during the period 2003-2006 (with a few later additions). The table can be sorted by author, date and length of discussion by clicking on the relevant word in the top line of the table.

Many of the tables of references on this website are considerably longer than the references to books found on most other UFO websites. Indeed, some are probably the longest that have been collated in relation to some events and personalities. Together with the "UFO Searchillion" search box, I hope that these tables are found to be a useful contribution to UFOlogy.

For discussion of the alleged Estimate of the Situation see the following:
