The 3,000 ARVN troops crossed the border in armored columns and by American-piloted helicopter troopships and reached a trail complex 20 miles (32 km) south of Xépôn (Tchepone), the key enemy supply center for the Communists.^[33] The South Vietnamese designation replaced the American code name of "Operation Dewey Canyon II", and was the 719th ARVN operation to honor the Lam Son uprising by the Vietnamese people in 1418 against the Chinese Empire.^[34]
• South Africa's white minority government eased its apartheid regulations to a degree by allowing mixed-race Africans ("Coloureds") to work in construction jobs formerly limited to whites only. Black South Africans were still barred from working on "white" projects in Pretoria, and the change in policy, prompted by a shortage of skilled workers, was limited to bricklayers and plasterers. Gert Beetge, the general secretary of the all-white Union of Building Workers, criticized the decision of the Labor Ministry and said that it marked "the death knell to white building workers".^[35]

Most of the deaths were in the collapse of the Olive View hospital and the VA hospital in Sylmar.
• The six member nations of the European Economic Community (EEC), also known as the "Common Market", approved a plan to create a common unit of currency over the next ten years.^[40] The European Currency Unit (ECU) would be implemented by 1979 for use in international transactions involving the EEC members (Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany) but the Euro would not be put in to circulation until 2002.

• Satchel Paige became the first primarily Negro league player to become voted into the Baseball Hall of Fame in Cooperstown, New York. Paige had played five full seasons in the American League after the integration of Major League Baseball, but was enshrined for his 18 years in the first and second Negro National Leagues and the Negro American League. The original plan by the Hall was to admit one Negro league player per year "as part of a new exhibit commemorating the contributions of the Negro leagues to baseball"^[41] to be honored plaques separately-located, but equal to those of the MLB players. After critics pointed out the irony of segregating the honor to the enshrined stars, the plan would be revised in time for Paige's formal enshrinement. At the time of the decision, only two African-American players— Jackie Robinson and Roy Campanella— were enshrined in the Hall of Fame. While both Robinson (for the Kansas City Monarchs) and Campanella (for the Washington Elite Giants) had also played in the Negro leagues, they had both been voted in for their MLB achievements.

• The "Tehran Agreement", obligating oil producers to pay a 55% tax rate on their exports of oil from six of the OPEC member states on the Persian Gulf (Saudi Arabia, Iran, Iraq, Kuwait, Qatar and Abu Dhabi of the United Arab Emirates) was signed by the representatives of 23 oil companies, all of whom faced an embargo by February 21. The accord was signed at the Iranian Finance Ministry shortly after 3:00 in the afternoon local time.^[59][11] A turning point in history, the agreement "passed the initiative in oil pricing from the multinational companies to the exporting countries", which would then steadily raise the price of petroleum during the rest of the 1970s.^[60] The original agreement was to immediately increase the price of a barrel (42 U.S. gallons) of crude oil by 35 cents (from a then-average price of $1.79 a barrel), followed by 5 cent increases annually, and had been negotiated by teams headed by Iranian Finance Minister Jamshid Amouzegar for the OPEC nations and by British Petroleum Chairman George Fraser, 2nd Lord Strathalmond.^[59]
• Poisonous fumes from a diesel fire killed 34 passengers and seriously injured 60 more on a train in Yugoslavia that had been halted in a tunnel outside of Vranduk, in what is now Bosnia.^[61] Most of the casualties were factory workers and miners who were among the 200 passengers. Investigators concluded that "nothing serious would have happened if the train had been in the open instead of a tunnel" and blamed the disaster on the train's engineer and fireman. An electrical spark had ignited diesel fuel in the locomotive's reservoir as it passed through the Vranduk tunnel, and the crew brought the train to a stop rather than exiting.

• On Decimalisation Day, the United Kingdom and Ireland both switched to decimal currency at 10:00 a.m.^[62] as banks opened for conversion of money. As a reporter pointed out to non-Britons, "The old currency, the most complicated in the world, divided the pound into 20 shillings and the shilling into 12 pence... Now the pound is divided into 100 new pence, each worth 2.4 American cents."^[63] The shilling and the florin were replaced by the five pence and ten pence coins, and unusual denominations like the half crown (2 shillings and a sixpence) and the guinea had no decimal coin equivalent. The popular sixpence remained legal tender until being phased out.^[64] The Republic of Ireland converted its currency on the same day,^[65] allowing Ireland and the UK's Northern Ireland to have a similar system. Retired permanently was the old system of pricing in pounds, shillings and pence, referred to as £sd for the abbreviations of Latin terms for the British pounds (librae or "£."), shillings (solidi or "s.") and pennies (denarii or "d.").^[66] Thus, 2 pounds, 7 shillings and five pence was "£2.7s.5p." but became £2.37 afterward. However, the Decimal Currency Board had announced that "£sd will be legal tender for up to 18 months after D-day and some shops will be pricing and giving change in £sd," with the changeover period ending on August 15, 1972.^[67] In addition to Ireland, the African nation of Malawi went decimal on the same day, along with Gibraltar, while the Gambia, Nigeria and Malta continued to use the old system.^[68]
• "President's Day" was celebrated as a legal holiday nationwide in the U.S. for the first time, as new federal legislation took effect moving the George Washington's birthday holiday from February 22 to the third Monday in February.^[69][70] Washington had been born on February 22, 1732 ("February 11, 1731" under the Julian calendar at the time); the third Monday only falls in a range from the 15th to the 21st of the month and never on the actual anniversary of his birth. The federal holiday would become popularly known as President's Day in that it comes between the birthdays of Abraham Lincoln (born February 12, 1809) and of Washington, both days that had been observed as state holidays in the past.
• The government of Poland announced that it was reversing the increase of food prices that had triggered nationwide rioting in December, and that prices would return to normal on March 1.

• Angry over proposed price increases for agricultural supplies proposed by the European Economic Community (EEC)'s Agricultural Commissioner, a group of Belgian farmers brought three cows into a meeting room in Brussels where the six EEC nations' ministers of agriculture were meeting to discuss pricing. The "Young Farmers Alliance" carried out what one reporter noted was "a major feat of cowherding" in that they "had succeeded in driving three cows... through swift swing doors, past security guards, up three flights of marble steps, through a press room, down a corridor and into the council chamber." France's Minister of Agriculture commented that "It was an event unworthy of the construction of Europe".^[72]
• In West Dallas, Texas, two heroin addicts abducted five law enforcement officers from the Dallas County Sheriff's Department and the Ellis County Sheriff's Office, killing three of them and wounding a fourth. The fifth deputy escaped and summoned help. The suspects would be apprehended four days later after an extensive manhunt.^[73][74][75]

• The first recording by the secret taping system installed by U.S. President Nixon was made. There were nine original microphones in the Oval Office––five in the president's desk and one on each side of the fireplace; and two in the Cabinet Room under the table near the president's chair. Years after the Watergate scandal, former White House Chief of Staff H. R. Haldeman would admit that it had been his suggestion to Nixon to make the system voice-activated rather than to be controlled by an on/off switch; Haldeman's thought at the time was "that this president was far too inept with machinery ever to make a success of a switch system."^[76][77] The first conversation, made sometime after 7:56 in the morning, was between Nixon and Alexander P. Butterfield and is saved as "Conversation 450-001" by the Nixon Library.^[78]

• In what was later dubbed the "fuddle duddle incident", Canadian Prime Minister Pierre Trudeau was accused of mouthing obscenities at Opposition MPs in the Canadian House of Commons in Ottawa. News reports tastefully reported that MPs sitting across from Trudeau had "accused him of mouthing a two-word expression commonly translated without profanity to mean 'get lost'" and that "The prime minister later told reporters that he had said 'fuddle-duddle or something like that'."^[80][81] The incident added the euphemism "fuddle duddle" to the Canadian vocabulary and has made the news annually ever since.^[82]

• For the first time in 12 years, England won The Ashes, the quadrennial Test cricket tournament against Australia, bringing the ceremonial cremation urn (containing the figurative ashes of the sport of cricket for the losing team) back to England.^[83][84] England was represented by the Marylebone Cricket Club, captained by Ray Illingworth and the 7-Test Series came down to the Seventh Test in Sydney, played over six days beginning February 12. In that England had won the Fourth Test on January 14 and four other matches were played to a draw with no winner, Australia would have retained possession of the Ashes if it could end the series as a 1–1 draw. England won by 62 runs (England 184 & 302 Australia 264 & 160).

• The U.S. Naval Undersea Warfare Center's Project Deep Ops, training pilot whales to retrieve submerged objects ran into a problem when "Ishmael" was released into the Pacific Ocean and used the opportunity to escape after three years in captivity. According to the final report on Project Deep Ops, "Ishamael was lost during an open-ocean training exercise. Several days were spent searching for him with surface craft and helicopters," without success. The whale's flight to freedom was aided by "a malfunctioning automatic direction finder system" that had been strapped to his back.^[91]

• The U.S. Emergency Broadcast System (EBS) sent an erroneous warning to all the nation's radio and television stations, meant to be a standard weekly test conducted by NORAD in Cheyenne Mountain in Colorado at 7:33 in the morning (9:33 a.m. Eastern time, 6:33 a.m. Pacific). Many stations didn't notice that the warning included the message authentication code word provided to all Federal Communications Commission (FCC) licensed stations on a quarterly basis. Those that did, and that verified the code word "hatefulness", broadcast the warning "This is not a test. A state of national emergency exists. This station will now go off the air. Please tune your dial to a station on the Emergency Broadcast System for a message from the President. This is not a test. This is not a test." Instructions were then given for how to locate the EBS station broadcast serving the area.^[92] Although the reason for the alert wasn't directly mentioned by announcers, the activation of the EBS for a nationwide emergency was normally reserved for a warning of an attack on the United States.^[93] All broadcast stations had heard the tone, followed by a teletype message with the authentication word that said "Message authenticator: Hatefulness – Hatefulness. This is an Emergency Action Notification (EAN) directed by the President. Normal broadcasting will cease immediately. All stations will broadcast EAN Message One preceded by the attention signal, per FCC rules. Only stations holding NDEA may stay on air in accord with their state EBS plan." Thirteen minutes later, news services informed broadcasters that a mistake had been made and that stations should disregard the order to go off the air, and the official cancel notice did not get sent until 10:30 Eastern time with the statement "Message authenticator: Impish- Impish. Cancel message sent at 09:33 EST. Repeat Cancel message sent at 09:33 EST."^[94] The mistake was traced to a long-time civilian employee of NORAD who mistakenly loaded the wrong tape when sending the message to all stations. He told reporters "I can't imagine how the hell I did it."^[95] The FCC later reported that a survey showed that only 8 percent of the nation's TV and radio stations went off of the air as directed by the alert; of the 92% that kept broadcasting, one-third said that they questioned whether the message was valid and another one-third didn't see the alert until after it had been canceled.^[96]
