The other ten members of the Politburo were Brezhnev, Prime Minister Alexei Kosygin, party ideologist Mikhail Suslov, Russian Federation premier Gennady Voronov, Russian first deputy premiers Kiril Mazurov and Dmitry Polyansky, and Ukraine Party First Secretary Pyotr Shelest.^[50]
• The last poll tax in the United States was outlawed when a three-judge panel of the Fifth U.S. Circuit Court of Appeals voided the requirement in Mississippi, in accordance with the U.S. Supreme Court's ruling in Harper v. Virginia State Board of Elections. Since 1890, a registered voter had to present receipts showing payment of the poll tax for the two preceding Januarys before being allowed to cast a vote in a Mississippi election.^[51] Ostensibly, the law had been justified as a fundraiser for the "common school fund", but the poll tax accounted for only 0.43% of Mississippi's education revenues.^[52] As a practical matter, the poll tax was a deterrent to participation by low income Southerners, and most African-Americans. Earlier in the year, similar decisions had outlawed the taxes in Texas, Alabama and Virginia.
• All 494 people on board the Norwegian cruise ship Viking Princess were saved from a fire that swept through the luxury ocean liner while it was sailing in the Caribbean Sea between Aruba and Curaçao, although three of the passengers died of heart attacks during their escape. "It's funny the way the passengers all stuck together," a passenger would later say, "It was a very peculiar thing. No shouting or screaming." The ship's captain, Otto Thoresen, said that it took the passengers only ten minutes to enter lifeboats after the 'abandon ship' order was given. At the time, the closest ship, the German vessel Cap Norte, was still 90 minutes away.^[53]
• Two boys, aged 13 and 12, who ran away from their homes in Fayetteville, North Carolina, sneaked on to a railroad box car and then found themselves locked inside for the next 13 days.

• United Nations Security Council Resolution 221 was adopted by a 10 to 0 vote, with five abstentions, and authorized the United Kingdom to use military force to enforce a U.N. embargo against Southern Rhodesia. Two permanent members, the Soviet Union and France, abstained, but did not veto the British-sponsored resolution. The vote authorized the Royal Navy to halt the Greek oil tanker Joanna V, already at anchor outside the Portuguese Mozambique port of Beira, from going any further and unloading its petroleum cargo for delivery through a pipeline to Rhodesia,^[60] and to stop the incoming ship Manuela from sailing into Beira.^[61]
• Nell Theobald, an American model who appeared in advertisements to promote various products, was injured on the job while posing with a lion named Ludwig as part of a photo shoot for BMW automobiles.^[62] Although Ludwig co-operated with the taking of multiple pictures during the International Automobile Show at the New York Coliseum, the lion bit Ms. Theobald on the left thigh when photography was over. The model required surgery to prevent her leg from being amputated, and would later receive a $250,000 settlement from a lawsuit against multiple defendants.

• The Central Committee of the Chinese Communist Party approved a directive that disapproved of almost all of the literary and artistic works that had been created since the 1949 founding of the People's Republic, on the ground that they reflected an "anti-party and anti-socialist black line... that combines bourgeois literary theory and modern revisionist literary theory" that was contrary to the thought of Chairman Mao. The ruling, sent out nationwide, made criminal suspects of China's artists and writers during the Cultural Revolution.^[66]

• At a news conference in Colorado, NASA Administrator James E. Webb stated that the AAP would be hampered by a lack of payloads unless Congress granted additional funds in the Fiscal Year 1968 budget. Efforts to obtain appropriations for post-Apollo projects were hindered by rising costs of the Vietnam War and congressional discontent with NASA's increasing administrative costs. Asked about the House Government Operations Committee's suggestion that NASA abandon AAP and participate in the Air Force's Manned Orbiting Laboratory program, Webb denied that "complete common use" of facilities was possible. He noted that many countries in which the United States had tracking facilities would not cooperate if those installations were used for military projects.^[32]
• The three convicted assassins of Malcolm X were each sentenced to life in prison, after having been found guilty of murdering the Black Nationalist leader at the Audubon Ballroom in New York City on February 21, 1965.

• NASA Associate Administrator for Manned Space Fight George E. Mueller informed Deputy Administrator Robert C. Seamans, Jr., of the Saturn/Apollo Applications Program Office's evaluation of a Lockheed proposal to launch space probes from orbit using Agena rockets launched from AAP stations in space. The proposal was feasible, Mueller advised, but did not seem a desirable mission for inclusion in the AAP. The other aspect of Lockheed's proposal concerned the development of techniques for launching vehicles from orbit. In this area, the chief contributions anticipated from AAP were assembly of large vehicles in orbit, fuel transfer, and preparation for orbital launch. Final checkout, which Lockheed proposed should be done by the astronauts, Mueller said could be accomplished more effectively by ground engineering groups through telemetry displays. Therefore, he recommended to Seamans that the proposal not be considered for inclusion in Saturn/AAP.^[32]
• MSC Director Robert R. Gilruth summarized Houston's position expressed during discussions with NASA Associate Administrator for Manned Space Flight George E. Mueller two days earlier. Gilruth cited NASA's need for a human spaceflight goal other than "using Apollo hardware" (and suggested a Mars flyby or landing mission as an in-house focus for planning). Also, he repeated his concern over the imbalance between AAP goals and resources, as well as the extent of engineering redesign and hardware modification that had been forced upon the project. Though expressing his and MSC's desire to contribute to and be a part of AAP, Gilruth voiced concern that "the future of manned space flight... is in jeopardy because we do not have firm goals, and because the present approach appears to us to be technically unsound."^[32]

• NASA Deputy Director Robert C. Seamans, Jr., told Associate Administrator for Space Science and Applications Homer E. Newell that he had no choice but to delay initiation of development competition on the Apollo Telescope Mount (ATM) until the AAP funding picture for the next two fiscal years became clearer. On the other hand, he said he recognized Newell's deep interest in the ATM project and its scientific value, and he was ready to proceed with advanced study work. Accordingly, he said he had signed the sole source award to Ball Brothers Research Corporation to study adapting the ATM for automatic observations in orbit beyond the basic 14-day crewed mission and to study adapting the ATM to the Apollo lunar module (LM) for extended crewed operations. Seamans expressed his own conviction that, to meet the objectives of the AAP mission at the earliest possible time, it would be best to mount the ATM directly on the Apollo command and service modules. If the present fiscal problem precluded such an arrangement, he told Newell, the agency would then be in a better position at a later date to decide whether the ATM should be included as part of the Apollo Lunar Module or whether some alternate approach should be used.^[32]
