SUBJECT: Project "SIGN"

Gentlemen:

This Headquarters is currently engaged in an intelligence investigation of all reported unidentified aerial phenomena. To date, no concrete evidence as to the exact identity of any of the reported objects has been received. Similarly, the origin of the so-called "flying discs" remains obscure. The possibility exists that some of the sighted objects are of domestic origin, i. e., unrecognized configurations of some of our latest aeronautical attainments, or that they are objects not readily recognized by the public - test vehicles in various stages of development, etc.

Where security regulations will permit, it is requested that your office submit to Hq, Air Materiel Command, Wright-Patterson AF Base, Wright Fld., Ohio, Attn: MCIAXO-3, THRU: Chief of Staff, USAF, Washington, 25, D. C., DIRECTOR OF INTEL, Deputy Chief of Staff, Operations, ATTN: AFOIR, any available evidence which might serve to indicate that these objects have a domestic origin.

Your cooperation in so doing might greatly assist in identifying our own domestic developments from possible inimical foreign achievements.

Very truly yours

H. M. McCOY
Colonel, USAF
Chief of Intelligence
