Here is the segment of what happened on this day in history.
“The Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin, was one of the last major offensives of the European theatre of World War II.
After the Vistula–Oder Offensive of January–February 1945, the Red Army had temporarily halted on a line 60 km (37 mi) east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.”
‘Osama bin Laden, the founder and first leader of the Islamist militant group al-Qaeda, was killed in Pakistan on May 2, 2011, shortly after 1:00 a.m. PKT by United States Navy SEALs of the U.S. Naval Special Warfare Development Group. The operation, code-named Operation Neptune Spear, was carried out in a CIA-led operation with Joint Special Operations Command, commonly known as JSOC, coordinating the Special Mission Units involved in the raid.
In addition to SEAL Team Six, participating units under JSOC included the 160th Special Operations Aviation Regiment (Airborne)—also known as "Night Stalkers"—and operators from the CIA's Special Activities Division, which recruits heavily from former JSOC Special Mission Units. The operation ended a nearly 10-year search for bin Laden, following his role in the September 11 attacks on the United States.’
“The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in cost and casualties. It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.
The accident occurred during a safety test on the steam turbine of an RBMK-type nuclear reactor. During a planned decrease of reactor power in preparation for the test, the power output unexpectedly dropped to near-zero. The operators were unable to restore the power level specified by the test program, which put the reactor in an unstable condition.”
“The Chaitén volcano entered a new eruptive phase for the first time since around 1640 on the morning of May 2, 2008. The Chilean government began an evacuation of the nearby town of Chaitén (population 4,200) and the surrounding area the same day, the main phase of which was completed by May 3, 2008. One elderly person died while at sea en route to Puerto Montt. By the afternoon of May 3, the plume of ash from the eruption had spread across Chile and Argentina to the Atlantic Ocean, contaminating water supplies, and reportedly coating the town of Futaleufú located 75 kilometres (47 mi) southeast to a depth of 30 centimetres (12 in). Ash thickness estimates are often exaggerated during volcanic crises; later field investigations suggest that the average ash thickness deposited across Futaleufú was less than 5–10 cm (2–4 in).”
