Suicide aircraft attacks on The World Trade Center and the Pentagon left untold numbers injured or dead and threw the cities into chaos on September 11, 2001. It began at the height of a morning rush hour in the nation's largest city. A plane, reportedly a hijacked American Airlines jet, slammed into one tower of the 110-story World Trade Center. As smoke and flames poured out of the building and rescue workers battled to save victims, a second plane hit the second tower. The two towers soon collapsed. Huge clouds of smoke hung over Manhattan. The nearby Wall Street financial markets were shut down. A short time later, another plane struck the Pentagon, touching off a massive explosion and fire, and tearing a hole in one side of the historic building.

Kaifeng, a prefecture-level city in eastern Henan province, People's Republic of China, located along the southern bank of the Yellow River, was flooded in 1642 by the Ming Dynasty army with water from the Yellow River to prevent the peasant rebel Li Zicheng from taking over. Roughly half of the 600,000 residents of Kaifeng were killed by the flood and the ensuing peripheral disasters such as famine and plague, making it one of the deadliest single acts of war in history (excluding systematic genocide) and the second greatest single loss of human life of its time.

Typhus is any one of several similar diseases caused by louse-borne bacteria. The name comes from the Greek typhos, meaning smoky or lazy, describing the state of mind of those affected with typhus. Rickettsia is endemic in rodent hosts, including mice and rats, and spreads to humans through mites, fleas and body lice. The arthropod vector flourishes under conditions of poor hygiene, such as those found in prisons or refugee camps, amongst the homeless, or until the middle of the 20th century, in armies in the field.

8 pandemics; hundreds of thousands killed worldwide
In the 19th century, Cholera became the world's first truly global disease in a series of epidemics that proved to be a watershed for the history of plumbing. Festering along the Ganges River in India for centuries, the disease broke out in Calcutta in 1817 with grand - scale results. When the festival was over, they carried cholera back to their homes in other parts of India. There is no reliable evidence of how many Indians perished during that epidemic, but the British army counted 10,000 fatalities among its imperial troops. Based on those numbers,, it's almost certain that at least hundreds of thousands of natives must have fallen victim across that vast land. Cholera sailed from port to port, the germ making headway in contaminated kegs of water or in the excrement of infected victims, and transmitted by travelers. The world was getting smaller thanks to steam-powered trains and ships, but living conditions were slow to improve. By 1827 cholera had become the most feared disease of the century.
