For thirteen days in October 1962 the world was on the brink of nuclear war - The Cuban Missile Crisis
Day 2, October 17
American military units begin moving to bases in the Southeastern U.S. as intelligence photos from another U-2 flight show additional sites; and 16 to 32 missiles. To avoid arousing public concern, the president maintains his official schedule, meeting periodically with advisors to discuss the status of events in Cuba and possible strategies.
President Kennedy attends a brief service at St. Matthew’s Cathedral in observance of the National Day of Prayer. After, he has lunch with Crown Prince Hasan of Libya, and then makes a political visit to Connecticut in support of Democratic congressional candidates.

I don’t think this is from the CMC. The date on it is 5-23-78 (May 23, 1978)
It was declassified in 1978.
