• The Battle of Ap Gu ended after two days in South Vietnam's Tay Ninh Province, as the 1st Battalion of the 26th Infantry of the U.S. Army's 1st Infantry Division overcame an attack by the much larger 9th Viet Cong Division. The battalion commander, Lt. Colonel Alexander M. Haig, would win the Distinguished Service Cross for his heroism in flying into gunfire and defending against multiple assaults against the American encampment; Haig would rise through the ranks quickly, becoming a general two years later, and retiring as a four-star general in 1979.^[2] The U.S. Army lost 17 men, compared to 609 Viet Cong soldiers.^[3]
• Radio Zurich, a radio network in Switzerland, played an April Fool's Day joke on thousands of its listeners, by frequently interrupting regular programming with bulletins about an American crewed landing on the Moon. Telephone lines were jammed, hundreds of people traveled out to the countryside to watch for the re-entry of the mission, and even the American consulate in Zürich called the UPI news bureau in an attempt to confirm the story. "Belief in the story was increased," a UPI dispatch noted, "because there are no week-end newspapers in Switzerland and television does not start broadcasting until 6 p.m."^[4]
• The United States Department of Transportation, created as a cabinet-level department separate from the U.S. Department of Commerce, began operations at 400 Seventh Street S.W. in Washington.

Journalists could also be incarcerated if they showed a lack of "due respect for institutions and individuals when criticizing political administrative action", including anything seen as an "attack" on the government of President Francisco Franco.^[12]
• In a speech titled Beyond Vietnam: A Time to Break Silence, his strongest antiwar declaration up to that time, Martin Luther King Jr. denounced U.S. involvement in Vietnam and related his own discussions with African-Americans in the past several months. "I could never again raise my voice against the violence of the oppressed in the ghettos," King said, "without first having spoken clearly to the greatest purveyor of violence in the world today, our own government." King, who would be assassinated exactly one year later, addressed a gathering at the Riverside Church in New York City.^[13][14]

• Corazon Amurao, the only eyewitness to Richard Speck's murder of eight nurses on July 13, 1966, testified in his criminal trial in Peoria, Illinois, and pointed him out as the man who had killed her roommates.

• Donald K. Slayton, Manned Spacecraft Center (MSC) Director of Flight Crew Operations, requested that the proposed T-020 "Jet Shoes" experiment be removed from all Apollo Applications Program (AAP) flights. The "Jet Shoes" experiment was an astronaut maneuvering system consisting of two small thrusters mounted one beneath each foot and oriented so that the thrust vectors passed close to the center of body mass with legs and feet in a comfortable position. During January, several astronauts tested an engineering development model of the "Jet Shoes" on the MSC air bearing facility. Although the tests by the astronauts were shirt-sleeve runs, a Langley Research Center (LaRC) test pilot made several runs in an inflated pressure suit. The results were unsatisfactory. In his objections to the experiment, Slayton suggested that its attempted use by an astronaut wearing a life support unit would provide extremely poor visibility.^[23]
• Bill Baird, an advocate for reform of restrictions against birth control, was arrested in front of 2,500 people at an auditorium at Boston University, shortly after announcing that he would challenge the Massachusetts state law. Baird handed a can of Emko spermicidal foam and a condom to a 19-year-old student and was taken off the stage by Boston police, who charged him with providing contraceptives to a minor, distributing medicines without a pharmacist or medical license, and "illegally exhibiting an obscene object".^[24] Baird would fight his conviction to the U.S. Supreme Court, which would, on March 22, 1972, reverse the lower courts in the case of Eisenstadt v. Baird.^[25]
• Marking the largest ransom in United States history up to that time, the president of a bank in Beverly Hills, California, paid $250,000 for the safe release of his 11-year-old son, who had been kidnapped from his home three days earlier.^[26] A few days short of three years later, Ronald Lee Miller, an investigator for the Internal Revenue Service, would be indicted for the crime before the 3-year statute of limitations expired.^[27] After his conviction, Miller would be sentenced to life imprisonment without parole.^[28] None of the ransom money would ever be found.^[29][30]
• "The City on the Edge of Forever", a favorite episode of fans of the TV show Star Trek, was telecast for the first time, at 8:30 p.m. Eastern time and again at 8:30 Pacific time.

Israeli tanks took up positions and fired back, and Syrian tanks then mobilized. At 1:30 in the afternoon, Israel's Mirage fighters began bombing and strafing the Golan Heights, and at 1:45, the Syrian Air Force scrambled its MiG-21s, which were all shot down in the battle, while the Israelis suffered no losses.^[33] The first air battle began at 1:58 when a pair of Mirages fired at two MiGs that were patrolling over the Syrian capital, Damascus. Israeli pilot Iftach Spector downed both planes with the assistance of his wingman, Beni Romach.^[34]

Using a robotic scoop called the Soil Mechanics Surface Sampler, the probe dug four different trenches and sent data back to Earth, revealing that the Moon soil was "like coarse damp beach sand, being cohesive and clumpy."^[95] On May 3, the Surveyor probe would power down as it entered a two-week long "night cycle", when temperatures on the darkened surface fell to -250 °F; after the cycle's end, however, engineers on Earth would try in vain to locate Surveyor's transmitter frequency to reactivate the craft, which "apparently froze to death" and would be declared a loss upon entering its second night cycle on June 1.^[96] The bouncing would later be traced to "unexpectedly high reflectivity" from rocks on the lunar surface "at a critical point in the touchdown"; nonetheless, the spacecraft "scored history's longest hole-in-one by hopping into a crater at the end of its quarter-million mile flight."^[97]

• James Earl Ray, a 39-year old convict serving a 20-year sentence for armed robbery, escaped from the Missouri State Penitentiary in Jefferson City.^[117] He would later tell interrogators that other inmates helped him conceal himself inside a four-foot by four-foot container that was used to deliver loaves of bread to prisons in the area, then helped load him onto a truck.^[118] Forty-nine weeks later, on April 4, 1968, Ray allegedly committed the assassination of Martin Luther King Jr. in Memphis, Tennessee, and would finally be recaptured on June 10 of that year at Heathrow Airport in London.^[119]
• The Soviet Union announced the launch of Air Force Colonel Vladimir Komarov on "a powerful new carrier rocket" as Soyuz 1 was sent into orbit at 3:35 a.m. local time from Baikonur on what was to be a 72-hour mission. In a separate announcement, the Soviet news agency Tass suggested that it would soon send up a second spacecraft that would link to Soyuz 1, and that the pilots would trade places.^[120][121] Soyuz 2 would have been launched the next day with Valery Bykovsky, Yevgeny Khrunov and Aleksei Yeliseyev, but Soyuz 1 began experiencing problems soon after launch.^[122]

• Soviet cosmonaut Vladimir Komarov became the first person to be killed during a spaceflight when the parachute of his space capsule Soyuz 1 failed during re-entry. The capsule crashed at 8:24 a.m. local time, 40 miles (64 km) east of the city of Orsk, and rescuers found that "the base of the spacecraft had been completely burned through" and that Komarov's remains had been burned into a "blackened lump measuring 30 x 80 cm".^[123] His launch the day before had been complicated by a drain of battery power caused by the failure of a solar panel to deploy, and he had made 18 orbits at a lower altitude than planned.^[124] On his last three circuits of the Earth, as the orbit was decaying due to friction, he was having difficulty controlling the vehicle before he made his emergency re-entry.^[122][125] In the investigation that followed, it was found that the parachute design for the Soyuz capsules had been faulty and that the manufacture and testing had been poor, resulting in "the chilling conclusion that had Soyuz 2 been launched, that crew would also have perished on its return."^[126]
• The Philadelphia 76ers defeated the San Francisco Warriors, 125–122, in game six of the NBA Championship series, to win the title. Playing at home, San Francisco had a 12-point lead in the third quarter.

• John A. Love, the Republican Governor of Colorado, signed a bill "giving Colorado the nation's most liberal abortion law. Under the law's terms, if a three member board in an accredited hospital agreed unanimously that a pregnancy met one of four specified conditions (death or serious impairment to the mother, the likelihood of a child being born with a "grave and permanent physical deformity or mental retardation", a pregnancy of less than 16 weeks arising from forcible rape or incest, or a girl under the age of 16 made pregnant by rape or incest).^[128] Previously, Colorado and other states in the U.S. allowed abortion of a pregnancy only in cases of "a severe threat to the physical health of the mother" or "pregnancies resulting from forcible rape"; Love said that letters and telegrams were "about 2,600 against and about 2,400 for the bill".^[129] On May 17, the state director of health and hospitals announced that a 12-year old rape victim would be given the first legalized abortion in the United States.^[130] The reform of the law took place in the wake of an increase of babies born with birth defects; North Carolina and California would make similar changes in their laws later in the year, and Georgia and Maryland would follow in 1968.^[131]
• Twenty-seven people in Kiev were killed when the bus they were on sank into the Dnieper River in the Ukrainian SSR. In a departure from the existing Soviet policy to not publicize accidents, the newspaper for the Ukrainian SSR Communist Party reported the accident nine days later. Government investigators concluded that the driver had "violated traffic rules by passing a truck, causing the bus to become accidentally hitched to a streetcar bumper", then swerved out of control and crashed through a guard rail. Only five people were rescued from the river.^[132]
• The colony of Swaziland was made a protectorate by the United Kingdom, with internal self-government. The Ngwenyama (Paramount Chief) of the Swazi people, Sobhuza II, was recognized as King and head of the government. Full independence would be granted on September 6, 1968.^[133]

• For the first time, a satellite was launched into orbit from an ocean platform. San Marco B, the second satellite in Italy's space program (and the first to be sent up from Kenya) soared into space under the direction of an all-Italian team of 100 scientists. From a converted oil drilling rig in the Indian Ocean, a few miles off the coast of Malindi, an American Scout B rocket carried the 285-pound (129 kg) research satellite into an equatorial orbit. The satellite's purpose was to gather "data on air density and ionospheric conditions above the earth's equator."^[135] It would re-enter the atmosphere on October 14 after 171 days in orbit.^[136]

• Died: U.S. Navy Lieutenant Commander Michael J. Estocin, 35, was shot down over North Vietnam while leading his second airstrike in six days from the USS Ticonderoga (CV-14), with a mission to destroy North Vietnamese thermal power plants at Haiphong and the surface-to-air missile sites defending the plants. On his first mission, Estocin took out three of the missile sites before his A-4 Skyhawk plane was damaged by an SA-2 Guideline missile. Despite the damage, he took out another missile site before gliding back to the Ticonderoga. On his final mission, Estocin's A-4 was struck by another missile, and he fired his own missiles before plunging to the ground. Estocin would be promoted posthumously to the rank of captain and would be awarded the Medal of Honor in 1978 for "conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty on 20 and 26 April 1967".^[137]

• World heavyweight boxing champion Muhammad Ali refused to take the oath of induction into the United States Army after reporting as scheduled to an induction center in Houston, Texas. Ali stood in line with 11 other inductees, underwent a physical examination, blood tests and x-rays, but refused to step forward when his name was called by Army Lt. Steven Dunkley. He then told Navy Lt. C. P. Hartman that he understood the penalties and said that his refusal was based on his religious beliefs. The World Boxing Association stripped Ali of his boxing title on the same day; he would not be allowed to fight for the title again until 1970.^[143][144] On June 20, Ali would be convicted of draft evasion, fined $10,000 and sentenced to five years in prison, but the U.S. Supreme Court would overturn the conviction on June 28, 1967.^[145]
• U.S. Army General William C. Westmoreland, commander of U.S. forces in the Vietnam War, spoke to a joint session of the U.S. Congress in hopes of raising a budget for additional servicemen beyond the 470,000 who were already in South Vietnam. As an author would note later, "Never before had a military commander addressed Congress while he was directing an ongoing war." Westmoreland told Congress that he would need a minimum of 80,500 more troops and hoped that he could have 200,000 more men at his disposal.^[146]
• U.S. Army Corporal Dennis Brown returned to his home in Hinckley, Ohio, five days after his parents had mistakenly been told that he had been killed in action in Vietnam. Corporal Brown took his girlfriend to a high school senior prom, then returned to duty at the end of May.^{[147][148][149]}

The final result of the referendum on the New England New State Movement was 155,544 "yes" votes and 184,823 "no" votes.^[152] Boundaries of the proposed new state stretched northwest from Newcastle to Walgett and included Muswellbrook and Gunnedah. If the measure had passed, a "yes" vote would have been required in a referendum of voters in New South Wales, and if that had succeeded, the Commonwealth would still have had to vote on approving the division.^[153][154]
• Fidel Castro announced that all intellectual property belonged to the world's people and that Cuba intended to translate and publish technical literature without compensation. "We proclaim publicly that we consider all intellectual products patrimony to which all humanity has a right," Castro said in a televised speech.^[155]
• Izvestia became the first daily newspaper in the Soviet Union to publish a comic strip.

• Under federal law, daylight saving time went into effect throughout the United States for the first time, with the 1966 Uniform Time Act mandating that clocks be set ahead one hour at 2:00 in the morning on the last Sunday in April and then turned back one hour on the last Sunday in October. However, the law provided that any state could seek exemption from compliance by the United States Department of Transportation, and five of the 50 states chose to effectively change time zones rather than to change their clocks. The legislatures of Michigan and Hawaii voted to be exempt, and Alaska applied for a delay so that it could delineate its time zones.^[162] In Indiana and Kentucky, which shifted from the Eastern to Central time zones, the matter was complicated further because local governments were allowed the option to move their clocks forward if they chose, such as Dearborn County, Indiana^[163] or Muhlenberg County, Kentucky.^[164]
• The British cabinet voted, 13 to 8, to seek the admission of the United Kingdom into the European Economic Community, referred to at the time as the "Common Market".
