Most stories about the Cuban Missile Crisis start with Oct. 16, 1962, when the president and his advisors were briefed on the missile sites on the island. A few start with Oct. 13, when the U-2 flight that photographed the sites took off. U-2 overflights would collect more information during the crisis along with other reconnaissance plans. After collecting all the information, U.S. intelligence agencies believed the Russians had smuggled nearly 10,000 troops onto the island.

Still, the Russian deception continued. They kept America convinced for some time that troop levels were small and America didn't know about the tactical nuclear weapons that were on the island for years.
