Among the incidents on the list is the 1994 crash of a secret American aircraft near a British Air Force base.
Although some locals managed to catch tantalizing glimpses of the downed craft, special forces were called in to guard the wreckage until it could be spirited away by American officials.
Although that event did not cause any injuries, the same cannot be said for another troubling accident detailed in the video: the ‘biological Chernobyl’ that erupted from a Russian chemical weapons facility in 1979.
While developing a deadly bacteria, the plant inadvertently released anthrax dust into the local atmosphere, killing 75 workers at a nearby ceramics factory.
Of course, the KGB made sure that all evidence of the malfeasance was quickly destroyed and the true nature of the event only came to light many years later.
A similar incident occurred in 1992 when a plane carrying Israeli military equipment crashed into an apartment building in Amsterdam.
When residents of the complex started becoming sick with mysterious illnesses, authorities attempted to determine what on the plane may have cause the odd outbreak and turned to the Israeli government for answers.
However, their role in the flight remained shrouded in secrecy until six years later when they conceded that the plane had been transporting chemicals used for making Sarin nerve gas.

The Battle of Mosul is a joint offensive by Iraqi government forces with allied militias, Iraqi Kurdistan, and international forces to retake the city of Mosul from the Islamic State of Iraq and the Levant (ISIL). The offensive, dubbed Operation “We Are Coming, Nineveh” (قادمون يا نينوى; Qadimun Ya Naynawa), began on 16 October 2016, with forces besieging ISIL-controlled areas in the Nineveh Governorate surrounding Mosul. The battle for Mosul is considered key in the military intervention against ISIL, which seized the city in June 2014. Outnumbering ISIL forces 10 to 1, it is the largest deployment of Iraqi troops since the 2003 invasion of Iraq.
The operation follows the Mosul offensives in 2015 and 2016. The offensive began with Iraqi troops and Peshmerga fighters engaging ISIL on three fronts outside Mosul, going from village to village in the surrounding area. More than 120 towns and villages were liberated from ISIL control in the first two weeks of fighting. At dawn on 1 November, Iraqi Special Operations Forces entered the city on the eastern front. Meeting with fierce fighting, the Iraqi advance into the city was slowed by elaborate defenses – including road blocks, booby traps, suicide bombers and snipers – and by the presence of civilians.
The Battle of Mosul is concurrent with the Battle of al-Bab by the Turkish-led FSA forces, and the Raqqa offensive by the Syrian Democratic Forces (SDF) on ISIL’s capital city and stronghold in Syria.
