Amelia Mary Earhart (/ˈɛərhɑːrt/ AIR-hart; born July 24, 1897; declared dead January 5, 1939) was an American aviation pioneer. On July 2, 1937, Earhart disappeared over the Pacific Ocean while attempting to become the first female pilot to circumnavigate the world. During her life, she embraced celebrity culture and women's rights, and since her disappearance has become a cultural icon.[2] Earhart was the first female aviator to fly solo across the Atlantic Ocean and she set many other records.[3] She was one of the first aviators to promote commercial air travel, wrote best-selling books about her flying experiences, and was instrumental in the formation of The Ninety-Nines, an organization for female pilots.[4]

The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo.[3] It was formed slightly over 66 million years ago when a large meteorite, about ten kilometers (six miles) in diameter, struck Earth. The crater is estimated to be 200 kilometers (120 miles) in diameter and 20 kilometers (12 miles) in depth. It is the second largest confirmed impact structure on Earth, and the only one whose peak ring is intact and directly accessible for scientific research.[4]

Operation Eagle Claw was a failed operation by the United States Armed Forces ordered by U.S. President Jimmy Carter to attempt the rescue of 52 embassy staff held captive at the Embassy of the United States, Tehran on 24 April 1980.
The operation, one of Delta Force's first,[1] encountered many obstacles and failures and was subsequently aborted. Eight helicopters were sent to the first staging area called Desert One, but only five arrived in operational condition.[2] One had encountered hydraulic problems, another was caught in a sand storm, and the third showed signs of a cracked rotor blade. During the operational planning, it was decided that the mission would be aborted if fewer than six helicopters remained operational upon arrival at the Desert One site, despite only four being absolutely necessary.[2] In a move that is still discussed in military circles, the field commanders advised President Carter to abort the mission, which he did.[3]

The Battle of Red Cliffs, also known as the Battle of Chibi, was a decisive naval battle in the winter of AD 208–209 at the end of the Han dynasty, about twelve years prior to the beginning of the Three Kingdoms period in Chinese history.[4] The battle was fought between the allied forces of the southern warlords Sun Quan, Liu Bei, and Liu Qi against the numerically superior forces of the northern warlord Cao Cao. Liu Bei and Sun Quan frustrated Cao Cao's effort to conquer the land south of the Yangtze River and reunite the territory of the Eastern Han dynasty.
