Dear Sir:
I have no further information regarding the individual described in your bulletin.
I offer for your consideration the use of a small radio transmitter which could be placed in a parachute or other equipment requested in the future by such a hi-jacker, that could be used for subsequent tracking and triangula- tion. I am thinking of a similar device used by the Air Force and I believe it is referred to as"SARA" which transmits a fixed radio frequency at certain intervals, and is used to find downed air craft and/or survivors.
I realize this would be of no value in the cur- rent investigation, but offer it for future reference.
Sincerely, [REDACTED - b6/b7C]
