will stop all ships entering Cuban waters and inspect them to verify they are not carrying weapons destined for Cuba. The Soviet Union sends mixed messages in response. Off the shores of Cuba, the Soviet ships turn back from the quarantine lines. Secretary of State Dean Rusk says, "We're eyeball to eyeball and I think the other fellow just blinked." The administration continues to order spy plane pictures, but one of Kennedy's top advisers, Kenneth O'Donnell, calls the pilots to ensure the pilots do not report that they were shot at or fired upon, because if they were, the country would be forced to retaliate under the rules of engagement. John A. Scali, a reporter with ABC News, is contacted by Soviet "emissary" Aleksandr Fomin, and through this back-channel communication method the Soviets offer to remove the missiles in exchange for public assurances from the U.S. that it will never invade Cuba. A long message in the same tone as the informal communication from Fomin, apparently written personally by Soviet Premier Nikita Khrushchev, is received. This is followed by a second, more hard line cable in which the Soviets offer a deal involving U.S removal of its Jupiter missiles from Turkey. The Kennedy administration interprets the second as a response from the Politburo, and in a risky act, decides to ignore it and respond to the first message, assumed to be from Khrushchev. There are several mis-steps during the crisis: the defense readiness level of Strategic Air Command (SAC) is raised to DEFCON 2 (one step shy of maximum readiness for imminent war), without informing the President; a nuclear weapon test proceeds (Bluegill Triple Prime) and a routine test launch of a U.S. offensive missile is also carried out without the President's knowledge. In a bid for time while under intense pressure from the military for an immediate strike, President Kennedy authorizes attacks on the missile sites and an invasion of Cuba, to commence the following Monday. An Air Force U-2 reconnaissance plane is sent over Cuba to gather intelligence for the attack, but is shot down, killing the pilot. After much deliberation with the Executive Committee of the National Security Council, Kennedy makes a final attempt to avoid a war by sending his brother, Robert F. Kennedy to meet with Soviet ambassador Anatoly Dobrynin on Friday night. Bobby reiterates the demand that the Soviets remove their missiles from Cuba,
