This briefing document has been prepared specially for Air Defense Command units. Its purpose is to present all aspects of Project Blue Book so ADC personal will have a better understanding of the goals of the project, be able to more accurately evaluate reports of unidentified flying objects and increase the quality of those reports that are forwarded.

According to the briefing Air Force didn't take the 'flying saucers' seriously but that did take seriously the phenomena, unidentified flying objects. This briefing covered three main points:

a. The general aspects of Blue Book to clear up any misconceptions that any one may have

b. How reports can be evaluated in the units

c. How to increase the quality of reports that are forwarded.

Then the document goes one by covering some of the reported sightings detailing the specifics and showing the way how can be handled a reported sighting of an unidentified flying object. The briefing gives a short history of how the phenomena started, considering Kenneth Arnold sighting as the starting point of the modern UFO era and continuing with the sightings and mass sightings of the late 40's and early 50's.
