HISTORICAL ARGUMENTS

 LaMia Flight 2933 (LMI2933) was an international passenger charter flight operated by an Avro RJ85. It departed from Viru Viru International Airport (Bolivia) to José María Córdova International Airport (Colombia) with 68 passengers and 9 crew members, piloted by Miguel Alejandro Quiroga Murakami. It crashed on November 28, 2016 at approximately 22:15 local time (UTC-5: 00). Among the passengers were players from the Brazilian soccer team Chapecoense, who were on their way to play the 2016 Copa Sudamericana final against Atlético Nacional.4 5 6 Six people survived the accident. The Colombian Civil Aeronautics Special Administrative Unit investigated the accident with the support of the British Air Accidents Investigation Branch.

The preliminary Colombian report indicated that the plane was traveling overweight and with fuel at the limit, and that the pilots wrongly decided not to make stopovers to refuel at the Alfredo Vásquez Cobo de Leticia or El Dorado de Bogotá airports. Furthermore, they did not inform air control of the fuel shortage until the last moment. They did not comply with the flight plan, which should not have been approved by the airport authorities.7

The final report of Aeronáutica Civil de Colombia, released on April 27, 2018, highlights that the LaMia company "did not comply with the minimum quantity of fuel requirements demanded in international standards, since it did not take into account the fuel required for fly to an alternate airport, the contingency airport, the reserve airport, or the minimum landing fuel

On April 25 and 26, 1986, the worst nuclear accident in history occurred in present-day northern Ukraine when a reactor at a nuclear power plant exploded and burned. The incident, shrouded in secrets, was a watershed moment in both the Cold War and the history of nuclear power. More than 30 years later, scientists estimate that the area around the ancient power station will not be habitable for 20,000 years.

The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after WWII. Starting in 1977, Soviet scientists installed four RBMK nuclear reactors at the nuclear power plant, which is located south of the present-day Ukraine-Belarus border.

Historical disaster

The world quickly realized that it was witnessing a historic event. Up to 30 percent of Chernobyl's 190 metric tons of uranium were in the atmosphere, and the Soviet Union eventually evacuated 335,000 people and established a 30-kilometer-wide "exclusion zone" around the reactor.

Initially, 28 people died from the accident and more than 100 were injured. The United Nations Scientific Committee for the Study of the Effects of Atomic Radiation has reported that more than 6,000 children and adolescents developed thyroid cancer after being exposed to radiation from the incident, although some experts have disputed this claim.

International researchers have predicted that ultimately some 4,000 people exposed to high levels of radiation could succumb to radiation-linked cancers, and that some 5,000 people exposed to lower levels of radiation could suffer the same fate. However, the full consequences of the accident, such as the impacts on mental health and subsequent generations, remain a subject of debate and study.

The remains of the reactor are inside a massive steel containment structure developed in late 2016. Containment and monitoring efforts continue and cleanup efforts are expected to continue until at least 2065.

The disappearance of the ARA San Juan (S-42) refers to the loss of contact with the submarine ARA San Juan (S-42) of the Argentine Navy that occurred on November 15, 2017 at 7:30 a.m. m. (local time) in waters of the Argentine sea, with 38 crew members and 6 tactical divers on board. After a year and two days the ship was found by a private company, with its entire crew dead, very close to the point of disappearance and in the place where it was supposed to be, at a depth of 907 m.2 The sinking and the Post-disappearance searches were affected by suspicions, irregularities, negligence, late or contradictory reports, internal struggles and conflicts with the families of the seafarers.

The incident became known to the press on the night of the following day and was officially reported two days later through an official statement from the Argentine Navy, 3 4 in which it was reported that the SAR (search and rescue) protocol had been initiated .5 .

On the third day, the Argentine government announced on Twitter that it had decided to accept international aid that included the appropriate equipment to search for the submarine and rescue the crew.6 7 The emergency triggered the alert issued by the International Office for Rescue and Escape de Submarinos (Ismerlo) that coordinated the dispatch of ships, aircraft, equipment and specialized personnel from eighteen countries that, added to Argentina, totaled more than 37 ships and aircraft, and 4,000 people in search operations over an area of ​​482,507 km², an area equivalent to the entire territory of Spain.
