The following events occurred in December 1968:

December 1, 1968 (Sunday)

• Rafael Caldera was elected the new President of Venezuela, but would not be declared the winner until more than a week later. Caldera, of the COPEI Party, was one of six candidates on the ballot, and won by only 31,000 votes, defeating ruling party candidate Gonzalo Barrios by a margin of 1,082,941 to 1,051,870.^[1] Incumbent President Raul Leoni was barred by the constitution from running for re-election. The night before the election, all six candidates appeared on television at the same time to announce that they would all respect the outcome of the voting.^[2]
• Pakistan's President Mohammed Ayub Khan announced major concessions to university and college students who had been rioting for the past three weeks, including the repeal of a 1961 law that allowed the Pakistani government to take away the college degrees of graduates who had been accused of subversive activities. Other reforms announced by Ayub Khan were to lower requirements for academic promotion, and a pledge to release opposition political leaders.^[3]
• Israel's Air Force destroyed two important bridges in Jordan that served as railroad and highway links between Amman and the cities of Ma'an and Aqaba, effectively dividing the kingdom's links between North and South Jordan. The destruction of the railroad bridge cut off access for Jordanian Muslims from making the pilgrimage to Mecca.^[4]

December 2, 1968 (Monday)

• All 39 people aboard Wien Consolidated Airlines Flight 55 were killed when their Fairchild F-27 turboprop plane crashed in Alaska during a violent snowstorm. The plane had taken off from Anchorage and was 15 minutes away from its scheduled arrival at the small village of Iliamna.^[5][6]

December 3, 1968 (Tuesday)

• The 50-minute television special Elvis (sponsored by American sewing machine manufacturer The Singer Company), taped in June with a live audience in Burbank, California, aired on NBC, marking the comeback of Elvis Presley after 7 years during which the legendary musician's career had centered on the movie industry. The eagerly-anticipated return of the "King of Rock and Roll" would prove to be the most watched special broadcast of the 1968 holiday season in the United States. One observer would later note that "the Elvis special was not just a ratings winner; it was also one of the most riveting pieces of television ever broadcast. It was Elvis at his rocking best, interacting with an audience as he never had on film or on programs such as The Ed Sullivan Show", and that "the '1968 Comeback Special' proved that the singer was still the most powerful live entertainer in the world. Millions who had never before listened to Elvis found themselves caught under the singer's spell."^[7] At the close of the show, Presley concluded with the premiere of "If I Can Dream", a song inspired by Martin Luther King Jr.. The show is followed by a Brigitte Bardot special.
• The international Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space, commonly known as the "Rescue Agreement", came into force, seven months after the United Nations had opened it for signature on April 22. The agreement does not apply to human space travelers who are stranded in outer space, only to those who require assistance on Earth and who are within the territorial limits of a participating nation, either on land or at sea, and makes no provision for how rescues are conducted or who bears the cost of a rescue.^[8]
• The Ohio State Buckeyes were granted a share of the survey-based national championship of college football, as the final UPI survey of 35 coaches ranked OSU in first place, ahead of the previous #1, the University of Southern California Trojans.^[9] USC had been unbeaten until its final game on November 30, when Notre Dame tied the game, 21 to 21. At the time, United Press International did not take a poll after the bowl games, so the results would be unaffected by the 1969 Rose Bowl, which would pit Big Ten champion Ohio State against Pacific Eight champion USC.

• U.S. President-elect Richard M. Nixon asked Earl Warren to delay Warren's retirement from serving as Chief Justice of the United States, and to continue until the end of the U.S. Supreme Court's current term in June. Despite Nixon's conservative stance and Warren's liberal view of the U.S. Constitution, both Nixon and Warren had both been the Republican Party's nominee for Vice President (Nixon successfully in 1952 and 1956, and Warren unsuccessfully in 1948), and both had been selected for national office by U.S. President Dwight D. Eisenhower.^[12]
• The Israeli Air Force added a new dimension to retaliatory airstrikes on neighboring Jordan, and attacked a division of the Army of Iraq, killing at least six of them and wounding 14. A spokesman for Israel charged that the Iraqi troops, which had been based in northern Jordan since 1967, had fired artillery shells at 12 Israeli settlements for three days.^[13][14]

December 5, 1968 (Thursday)

• The Czechoslovakian government announced the dismissal of Peter Colotka, who had been the Deputy Premier responsible for censorship of the news media, and whose liberal policies had given reporters and publishers room to criticize the government. Communist Party First Secretary Alexander Dubček, who had been forced by the Soviet Union to retract many of the reforms of the Prague Spring, told a crowd in the city of Most that the government would take steps to make the Czechoslovakian press "an instrument which will help to implement the policy of the Party" in order to prevent upheaval.^[15] Six months later, Colotka would be appointed as the Premier of the Slovak SR section of Czechoslovakia.
• The U.S. Securities and Exchange Commission outlawed "give-ups", the sharing of commissions between brokers earned from the sale of stock^[16] and relaxed its rules for a minimum commission rate by permitting discounted rates for large transactions. The result would be a decrease of business on regional stock exchanges outside of the New York Stock Exchange and the American Stock Exchange, both located in New York City.

• Abdul Hamid Khan Bhashani, the leader of the Bengali Muslims in East Pakistan (now Bangladesh) called on his followers to initiate a total shutdown of work in protest of the crackdown by Pakistani police on protesters. The hartal — a complete refusal by workers, students and shopkeepers to work — happened two days later, and a "Repression Resistance Day" would be observed throughout East Pakistan on December 10. The escalating protests would lead to "Mass Upsurge Day" on January 24.^[17]
• The Rolling Stones released the album Beggars Banquet, which contains their hit single "Sympathy for the Devil."^[18]

December 7, 1968 (Saturday)

• In one of the worst peacetime disasters for the United States Coast Guard, 17 crewmen of the USCGC White Alder (WLM-541) were killed when the buoy tending ship was sheared in half by the Taiwanese freighter Helena.^[19] Both ships were near White Castle, Louisiana, when the collision occurred and the ship sank in 75 feet (23 m) of water. Although three bodies were recovered by divers, a release from the U.S. Coast Guard would recount in 2017, "river sediment buried the cutter so quickly that continued recovery and salvage operations proved impossible. Fourteen Coast Guardsmen remain entombed in the sunken cutter buried on the bottom of the Mississippi River."^[20] An aid to navigation structure and light now marks the site of the sinking.
• The French government chartered the Centre universitaire expérimental de Vincennes, an experimental university, in Vincennes, an eastern suburb of Paris, as a campus of the University of Paris system.

December 8, 1968 (Sunday)

• Project Schooner, one of the 27 nuclear American tests conducted as part of Project Plowshare, took place at the Nevada Test Site and became noteworthy for the amount of radioactive contamination that it generated around the world. Although Schooner was an underground blast at the depth of 106 metres (348 ft), radionuclides such as strontium-90, barium-140, tungsten-181 and cesium-134 went 5,000 metres (16,000 ft) into the atmosphere and traveled over the North Pole into the Soviet Union within a week.^[23]

The new UTU was created from the Brotherhood of Railroad Trainmen, the Brotherhood of Locomotive Firemen and Enginemen, the Order of Railway Conductors and Brakemen, and the Switchmen's Union of North America. Charles Luna, the Railroad Trainmen leader who was designated as the first UTU President, announced in Cleveland that the overall referendum results in the four component unions had been 97,728 in favor and 15,067 opposed. Members of another organization, the Brotherhood of Locomotive Engineers, had rejected the merger.^[29]
• The largest heist in the history of Japan, the never-solved "300 million yen robbery", occurred in the Tokyo suburb of Kokubunji. A man dressed as a police motorcyclist pulled over an armored car that was taking holiday bonus money from the Japan National Bank to the Toshiba factory in Fuchu. The "policeman" ordered the driver and three guards to get out with a warning that the vehicle was on fire, then climbed into the cab and drove off with ¥294,307,500 (worth US $817,667 at the time and nearly $5.8 million or more than one billion yen fifty years later).^[30][31]

The diversion of the river affected 437 acres (177 ha) of sagebrush covered land, previously north of the Rio Grande in the U.S., and now south of the border as Mexican territory.^[37] The buttons weren't actually connected to the detonator, and an engineer was to carry out the actual blast, but the explosive charge failed; engineers quickly bulldozed the dam so that the ceremony could be completed.^[38]
• The day after being defied by the Brazilian Congress, President Artur da Costa enacted Institutional Act Number 5 (AI-5), closing Congress and suspending all constitutional rights indefinitely. AI-5 would remain in effect for more than a decade until its revocation in 1979, and Brazil would be ruled by decree by the military dictatorship.^[33]

Dr. Lloyd W. Bailey, one of the 13 Republican electors in North Carolina, cast his vote for George Wallace rather than for Richard Nixon. As a result, Nixon received 301 of the 538 votes rather than 302, and Wallace got 46 instead of 45. Hubert Humphrey received all 191 of his pledged electors.

• High school students David Faraday and Betty Lou Jensen were shot and killed while parked along Lake Herman Road near Benicia, California, becoming the first confirmed victims of the Zodiac Killer.^[68] For six months, police had no leads, until a man claiming to be the killer called them from a pay telephone. In late July, after another murder, three San Francisco area newspapers would receive a letter that began, "Dear Editor: I am the killer of the 2 teenagers last Christmas at Lake Herman... To prove this I shall state some facts which only I + the police know." Each of the three letters included a piece of a 408-symbol cryptogram.^[69] On August 7, the killer would write again with the words "This is Zodiac speaking." In the fifty years after the killings, no person would ever be tried for the Zodiac killings.^[70][71]

• At 10:47 a.m. (15:47:05 UTC), Apollo 8 became the first crewed space vehicle to break out of Earth's orbit,^[78] and the three American astronauts on board — Frank Borman, Jim Lovell, and William Anders — went further from Earth than any people in history. The spacecraft had been launched from Cape Kennedy at exactly 7:51 local time and reached a 118-mile (190 km) high orbit in 11 minutes. At 10:41, the ignition for translunar injection started and within minutes, the astronauts not only exceeded the previous record distance from Earth of 848 miles (1,365 km), set by the crew of Gemini 11 on September 13, 1966, they reached the fastest speed ever attained by human beings, peaking at 24,227 miles per hour (38,990 km/h) to reach the escape velocity needed to leave Earth's gravitational well.^[79] The December 21 date had been selected so that the mission would be able to view the Sea of Tranquility when it was in lunar sunrise (i.e. within the lit portion of a waxing Moon as viewed from Earth) and the long shadows would allow the crew to photograph the future landing site when it was in sharp topographic relief.^[80]
• Forty-three people were killed, and 57 more hospitalized, after the train they were on collided with a freight train in Hungary. Most of the dead were travelers who were going home or on vacation for the Christmas holiday. The date would be reported as Sunday, December 22, in reports that reached western Europe,^[81] but the official 1984 report by the MAV, the Hungarian State Railway stated that the accident happened at 5:00 in the evening, between Sülysáp and Mende. Passenger train no. 6616/a collided head-on with the much heavier freight train no. 5565 near the Pusztaszentivan station.^[82]
• Only 38 of the 95 passengers and crew on the fishing schooner Federal Queen survived after the vessel capsized while bringing construction workers back to their homes on St. Vincent for the holidays.

According to survivors, the disaster happened when people who were on deck rushed to the leeward side of the boat after being drenched by spray from the rough seas.^[83]

December 22, 1968 (Sunday)

• At 11:30 in the morning local time, North Korea released the 82 members of the U.S. Navy ship USS Pueblo after 11 months of captivity that had started when the American ship was seized by North Korean ships on January 23.^[84] The handover of the men, along with the body of Seaman Duane D. Hodges (who had been killed when the Pueblo had been fired upon), took place at the border at Panmunjom after U.S. Army Major General Gilbert H. Woodward signed a statement of apology on behalf of the U.S. State Department, bringing an end to months of negotiation with North Korean Major General Pak Chung-kuk.^[85] The Pueblo itself was kept by the North Koreans and would later be put on display as a tourist attraction in Pyongyang.^[86] The freed crewmen were flown to Miramar Naval Air Station near San Diego on Christmas Eve for a reunion with their families.^[87]
• The Down to the Countryside Movement decree, by Chinese Communist Party Chairman Mao Zedong, was announced in the Party newspaper People's Daily.

We must persuade the urban cadres and others to send their offspring who are junior and senior middle-school and university graduates to the countryside... Comrades of the various villages ought to welcome them." The "rustication movement", referred to in China as the xiaxiang ("sent-down"),^[88] would last for more than 10 years; the Chinese government would report at its end that there were 16,230,000 students who participated, with most school graduates leaving for rural work rather than university education.^[89]
• On Apollo 8, astronaut Frank Borman vomited while in orbit, the day after taking a dose of the barbiturate drug Seconal, leaving the three astronauts with the task of the floating particles in a weightless environment. The episode marked the first experience of space-sickness by an American astronaut. In order to keep NASA from ordering the mission to be aborted before the spacecraft could pass the point where it could return without a slingshot trip around the Moon, Borman waited for a while to report that he was ill, and sent a taped message back to Earth.^[90]
