Editing Project Grudge (section)

== Conclusions ==

Project Grudge issued its only formal report in August 1949. The report's conclusions included:

: ''A. There is no evidence that objects reported upon are the result of an advanced scientific foreign development; and, therefore they constitute no direct threat to the national security. In view of this, it is recommended that the investigation and study of reports of unidentified flying objects be reduced in scope.''
: ''B. All evidence and analyses indicate that reports of unidentified flying objects are the result of:''
:: ''1. Misinterpretation of various conventional objects.''
:: ''2. A mild form of mass-hysteria and war nerves. ''
:: ''3. Individuals who fabricate such reports to perpetrate a hoax or to seek publicity. ''
:: ''4. Psychopathological persons.''

The "Recommendations" section suggested that Air Force personnel receive basic instruction in astronomical phenomena.
