Welcome to September 28! Today, Self Awareness Day encourages us to recognize our shortcomings, while Ask a Stupid Question Day gives us an opportunity to demonstrate them publicly. Be a good neighbor, celebrate the beautiful state of North Carolina, and reward yourself with a generous slice of Strawberry Cream Pie. After all, self-awareness is important, but knowing when to stop eating pie is an entirely different matter!

On July 2, 1865, William Booth and his wife, Catherine Booth, founded the Christian Mission in London's East End. Their goal was to bring practical help and Christian teaching to people struggling with poverty and hardship. Inspired by military organization, Booth introduced ranks such as officers and recruits, believing discipline and structure would strengthen the movement. Women were given leadership roles alongside men, an uncommon practice for the time.
The Christian Mission quickly expanded its work into some of London's poorest communities, opening soup kitchens and offering both physical assistance and spiritual support. Its energetic public preaching and unusual methods were not welcomed by everyone, and members frequently faced hostility, fines, and even imprisonment as authorities attempted to curb their activities.
In 1878, the organization adopted the name the The Salvation Army, and two years later established its first branch in the United States. During the Great Depression and both World Wars, the organization became widely respected for providing food, shelter, and support to civilians and military personnel alike. Today, the Salvation Army operates in more than 130 countries, delivering disaster relief, rehabilitation programs, community services, hospitals, thrift stores, and other charitable initiatives, supported through donations and the proceeds of its retail operations.
On September 28, 1066, William, Duke of Normandy, landed with his invasion force at Pevensey on the southeastern coast of England, determined to claim the English crown. William was the son of Robert I, Duke of Normandy, and Arlette of Falaise, and became duke while still a child following his father's death in 1035. His early rule was plagued by rebellions and political violence, but William survived the turmoil and developed into a formidable military and political leader. His eventual claim to England rested partly on his assertion that the childless King Edward the Confessor had promised him the throne. When Edward died in January 1066, however, the crown went instead to the powerful English nobleman Harold Godwinson, who became King Harold II. William refused to accept the succession and began preparing an invasion.
Harold faced another threat from the north before William could cross the English Channel. The Norwegian king Harald Hardrada joined Harold's estranged brother Tostig in an invasion of England, forcing the English king to march his army north. On September 25, Harold won a decisive victory at the Battle of Stamford Bridge, where both Hardrada and Tostig were killed. Just three days later, while Harold's exhausted forces were still recovering from their remarkable march and battle, William landed at Pevensey with an army numbering several thousand men. He established his position on the coast and moved toward Hastings, while Harold hurried south to confront this second invasion.
The armies met at the Battle of Hastings on October 14, 1066, in a brutal engagement lasting most of the day. Harold was killed during the fighting—traditionally said to have been struck in the eye by an arrow, although the circumstances of his death remain uncertain—and the English army was defeated. William advanced toward London and secured the submission of England's leading nobles before being crowned King William I at Westminster Abbey on Christmas Day. The Norman Conquest profoundly altered England's government, aristocracy, culture and language, while William's later reign produced the extraordinary Domesday Book, an extensive survey of landholding and wealth throughout much of the kingdom. The duke who stepped ashore at Pevensey in September 1066 would consequently become far better remembered by another name: William the Conqueror.
On September 28, 1965, Fidel Castro announced that Cubans who wanted to leave the country could do so, setting in motion another major wave of migration from Cuba to the United States. Relations between Havana and Washington had deteriorated dramatically since Castro's 1959 revolution, particularly after Cuba aligned itself with the Soviet Union, the failed Bay of Pigs invasion in 1961 and the Cuban Missile Crisis the following year. Thousands of Cubans had already fled the island, but Castro's announcement opened another route for people wishing to depart, many of whom had relatives already living in the United States.
The Cuban port of Camarioca became the departure point for an improvised boatlift as Cuban Americans sailed across the Florida Straits to collect relatives. The operation quickly became dangerous and difficult to manage, prompting negotiations between the governments of Cuba and the United States despite their bitter political hostility. The result was a more orderly airlift commonly known as the Freedom Flights. Beginning later in 1965, regular flights carried Cubans from the island to Florida, eventually becoming one of the largest organized refugee movements in American history.
The Freedom Flights continued into the early 1970s and brought hundreds of thousands of Cubans to the United States, with South Florida receiving a particularly large share of the newcomers. Miami already possessed a rapidly growing Cuban exile community, but the additional migration strengthened its transformation into a major center of Cuban American life, business and culture. The movement also had consequences for Cuba, which lost professionals and other skilled workers along with political opponents and people seeking greater economic or personal opportunities abroad. The migration permanently reshaped communities on both sides of the Florida Straits and added another significant chapter to the long and complicated relationship between Cuba and the United States.
On September 28, 1994, the passenger ferry Estonia sank in the Baltic Sea while making an overnight voyage from Tallinn, Estonia, to Stockholm, Sweden. The vessel was a roll-on/roll-off ferry, designed with a large vehicle deck that allowed cars and trucks to be driven aboard through the bow. Carrying passengers, vehicles and crew, the Estonia encountered severe weather during the crossing, with strong winds and heavy seas battering the ship. Shortly after midnight, the ferry developed a serious list and began taking on large quantities of water. It sank rapidly, leaving those aboard with very little time to escape.
The speed of the disaster made evacuation extraordinarily difficult. Many people were trapped below deck as the ship tilted sharply, while others who reached the open decks faced darkness, violent seas and dangerously cold water. Ships and helicopters rushed to the area, but the conditions severely hampered rescue efforts. Of the 989 people aboard, only 137 survived; 852 passengers and crew members died. The disaster became one of Europe's deadliest peacetime maritime tragedies of the 20th century and led to increased scrutiny of the design and safety procedures used aboard roll-on/roll-off passenger ferries.
An official investigation conducted jointly by Estonia, Finland and Sweden concluded that the ship's bow visor failed in the rough seas, allowing the loading ramp to open and seawater to flood the vehicle deck. The resulting loss of stability caused the Estonia to capsize and sink. Questions and competing theories about the disaster persisted for decades, particularly after later examinations revealed previously undocumented damage to the wreck's hull. Further investigations have continued to examine that evidence, although investigators have not established an explosion or collision as the cause of the sinking. The wreck remains on the Baltic seabed as both the site of an enduring investigation and a grave for hundreds of those who died.
On September 28, 2018, the container ship Venta Maersk arrived in St. Petersburg after completing a pioneering voyage across Russia's Arctic coast. The vessel had departed Vladivostok in August and traveled through the Northern Sea Route, which follows the Siberian coastline and provides a substantially shorter connection between parts of East Asia and northern Europe than the traditional route through the Suez Canal. Although other commercial vessels had already navigated Arctic waters, the voyage attracted particular attention because the Venta Maersk was a newly built container ship testing whether the route might eventually become practical for this important sector of international shipping.
Navigating the Arctic had challenged explorers and merchants for centuries, with generations searching for northern passages that could shorten the journey between Europe and Asia. The Venta Maersk, specifically constructed to operate in icy conditions, completed its 2018 voyage with assistance from an icebreaker during part of the journey. Maersk described the trip as a trial rather than the beginning of a new regular service, intended to gather information about navigation, equipment and operating conditions along the route. The Northern Sea Route remained difficult and highly seasonal, requiring suitably strengthened vessels and presenting navigational and logistical challenges not encountered on established shipping corridors.
The successful voyage nevertheless illustrated how changing conditions in the Arctic were creating possibilities that had once been largely inaccessible to commercial shipping. Arctic sea ice has declined substantially over recent decades as the region has warmed, extending the periods during which some northern waters can be navigated. That has generated commercial interest in shorter routes while also raising significant environmental concerns, including the consequences of increased shipping in a particularly vulnerable ecosystem. The Venta Maersk therefore completed more than an unusual journey between two Russian ports: its arrival in St. Petersburg became a striking example of how changes in the Arctic environment could influence the future geography of international trade.
On September 29, 1941, Nazi forces began the mass murder of Jewish residents of Kyiv at Babi Yar, a ravine outside the German-occupied Ukrainian city. German troops had captured Kyiv ten days earlier, and SS and police units soon prepared to carry out the systematic killing of the city's Jewish population. Notices ordered Jewish residents to assemble with their belongings, leading many to believe they were being relocated rather than taken to their deaths.
Over September 29 and 30, victims were forced toward the ravine in groups, made to surrender their possessions and clothing, and then shot. According to the United States Holocaust Memorial Museum, German reports recorded 33,771 Jewish people murdered during those two days, making Babi Yar one of the largest single mass shootings carried out during the Holocaust.
The ravine continued to serve as an execution site during the German occupation. Jews, Roma, Soviet prisoners of war, resistance members and others were murdered there, with estimates of the total number of victims reaching approximately 100,000. As Soviet forces approached Kyiv in 1943, the Nazis attempted to destroy evidence by forcing prisoners to exhume and burn bodies. The effort failed to erase the evidence, and Babi Yar remains one of the most powerful symbols of the Holocaust by bullets and the mass murder committed by Nazi Germany in occupied Eastern Europe.
On September 29, 1982, a series of mysterious deaths began in the Chicago area when people who had taken Extra-Strength Tylenol capsules suddenly became critically ill. The first victim was 12-year-old Mary Kellerman, who had been given Tylenol for cold symptoms. That same day, Adam Janus died after taking the medication, followed by his brother Stanley and Stanley's wife, Theresa, who unknowingly took capsules from the same bottle while grieving at Adam's home. Investigators eventually determined that capsules in several bottles had been deliberately contaminated with potassium cyanide.
Seven people ultimately died, with Mary Reiner, Mary McFarland and flight attendant Paula Prince among the other victims. As investigators searched for a common connection, authorities realized that each had taken Extra-Strength Tylenol shortly before becoming ill. Johnson & Johnson responded by recalling Tylenol capsules nationwide and warning consumers not to use the product. Although the poisoned bottles were traced to stores in the Chicago area, investigators concluded that the contamination had occurred after the medicine left the manufacturer, suggesting someone had altered bottles and returned them to store shelves.
The murders triggered nationwide alarm and permanently changed the way medications and many other consumer products are packaged. Manufacturers introduced increasingly sophisticated tamper-evident seals and abandoned easily opened capsules in favor of more secure alternatives, while federal legislation made tampering with consumer products a specific crime. Investigators pursued numerous leads—including an extortion attempt demanding money from Johnson & Johnson—but no one has ever been convicted of the seven murders. The Chicago Tylenol killings remain one of America's most notorious unsolved poisoning cases and fundamentally changed consumer expectations about product safety.
On September 29, 1988, Oregon mountaineer Stacy Allison became the first American woman to reach the summit of Mount Everest. Climbing as part of the Northwest American Everest Expedition, Allison reached the top by way of the mountain's southeast ridge. Rising 29,032 feet above sea level according to the elevation officially recognized today, Everest presents climbers with extreme cold, unpredictable weather and dangerously thin air, making even survival near the summit a formidable challenge.
Mount Everest rises along the border between Nepal and Tibet in the Himalayas and is known as Chomolungma in Tibetan and Sagarmatha in Nepali. The mountain received its English name in honor of Sir George Everest, a former Surveyor General of India. New Zealand mountaineer Edmund Hillary and Tenzing Norgay, a Sherpa mountaineer from Nepal, made the first confirmed ascent of Everest in 1953. American James Whittaker reached the summit with Nawang Gombu in 1963, while Japan's Junko Tabei became the first woman to reach the top in 1975.
Everest continued to produce major mountaineering milestones during the following years. Reinhold Messner and Peter Habeler completed the first ascent without supplemental oxygen in 1978, demonstrating that a feat previously considered nearly impossible could be achieved. A decade later, Allison added her own name to Everest history when she reached the summit, opening another important chapter for American women in high-altitude mountaineering. Her achievement was particularly significant in a sport in which relatively few women had yet been given opportunities to participate in major Himalayan expeditions.
On September 29, 2006, Weston High School principal John Klang was fatally shot by 15-year-old student Eric Hainstock at the school in Cazenovia, Wisconsin. Hainstock had taken firearms from his family's home and brought them to school that morning. After he pointed one weapon at a teacher, a custodian managed to take it from him. Hainstock still had another gun, however, and encountered Klang in a hallway. Although seriously wounded, the principal confronted the teenager, wrestled him to the floor and helped prevent further violence before other students and staff members took control of the situation. Klang later died from his injuries.
Hainstock had received a disciplinary warning from Klang the previous day after bringing tobacco onto school property and later said that he was also angry about bullying he believed school officials had failed to stop. He was prosecuted as an adult and, in 2007, was convicted of first-degree intentional homicide. He received a life sentence with the possibility of parole after serving 30 years. Klang, meanwhile, was widely remembered for confronting the armed student despite having already been wounded, actions credited with helping protect others at the school.
The Wisconsin shooting occurred during a particularly grim period of school violence in North America. Earlier that month, a gunman killed a student and wounded others at Dawson College in Montreal, while another attacker took students hostage and killed Emily Keyes at Platte Canyon High School in Colorado. Just three days after Klang's death, five girls were murdered at an Amish schoolhouse in Nickel Mines, Pennsylvania. The succession of attacks renewed public concern about school security and violence, while Klang's actions became an enduring part of how the Cazenovia community remembered the tragedy.
