The next step was to discover how far advanced the earlier SAM sites were. This information could be obtained only by taking the risk of overflying an SA-2 site that might be operational. At an interdepartmental group meeting on October 4th, the DCI made a strong representation for extensive overflights of Cuba. The group requested @MMMCS, and CIA to examine all alternative means of conducting aerial reconnaissance and to report back as soon as possible. A meeting was called on October 9th to hear this report, and at this meeting the flight was planned which was actually flown on the 14th of October. Additionally, from September 18th through October 2nd, agent and refugee reports dovetailed sufficiently to create a suspicion that there was something of unusual importance going on in a definite area west of Havana and that this unusual activity might be concerned with MRBM's. These reports, however, were not of sufficient credibility to warrant their being used in intelligence publications. Accordingly, the track of the flight planned at the October 9th meeting to test the operational readiness of the known SAM sites was drawn to cover the area in which MRBM's were suspected. - 10 - SECRET
