The following is an exact copy of the letter Ingo Swann sent endorsing the Coordinate Remote Viewing* Manual published by the Defense Intelligence Agency on 1 May 1986, with Paul H. Smith as primary author and editor.
As described here, Smith, with significant assistance from the other military CRV students of Ingo Swann and Hal Puthoff drafted the manual. Upon its completion, Capt. F. (“Fred”) Holmes Atwater, the training and operations officer for the remote viewing unit, forwarded a copy to Ingo Swann for his examination. Ingo sent the following signed letter in reply. After receipt, Atwater framed the original and presented it to Smith, who still has it in his possession.
(One clarification: Though Ingo was under the impression that Ed Dames had contributed to this manual, Dames had sometime before returned to his home unit and was not assigned to the remote viewing program until the manual had been substantially completed.)
*Now at the request of Ingo Swann called “controlled remote viewing”
