PIC Support of the U. S. Preparatory Group
for Technical Discussions on Safeguards
Against Surprise Attack
1. s initially reported in my memorandum of 16 October 1958, PTC
continues ure of support to the Air 3paee 3uh-
Group of the subject U. S. Preparatory Group.
2. We have Just finished the preparation of an index, ''Coaparisons
of Aerial Reconnaissance Sensors", end forwarded five (5) copies to the
Air 3paee 3ub-Group. A copy is attached for your information and
retention. This is a rather unique document vhieh like all things will
be the subject of discussion and probable modification. The Air Space
-13b-Group feels that it will be most useful back up data for its die-.
cuions with the 3ov1ets starting next week in Geneva.
3. Alao under preparation in our laboratories at the present time
another volume which will consist of indexed photogrephic samples
illustrating the results or simulated results achievable with a 36"
focal length lens.film system at 5,000', 50,000' and 150 miles with a
re*ultant resolution of some 25 lines/mm. In addition many large well
paper-type enlargements are being prepared for the graphic displays
and difJcussions at Geneva.
4. It continues to be difficult to support the Air 'Space Sub-Group
in Aeeting its sohedule. The other members of the ;ub-Group have been
an3igned to it on a hal time basis while we have carried on with our
regular work prioritise and fitted in the production for the Sub-Group,
sometimea on an overtins basis, as best we could. The last of our
reproductions are scheduled now to be delivered to the 3Ub-Group on
TUesday, 4 November 1958. Thereafter, we would expect to remain in
standby to provide such other technical data or displays as might be
requw3ted during the course of the discussions at Geneva.
