William McPherson "Bill" Allen (September 1, 1900 – October 28, 1985) was a U.S. aircraft businessman.
USS "Midway" (CVB/CVA/CV-41) was an aircraft carrier of the United States Navy, the lead ship of her class.
 Commissioned a week after the end of World War II, "Midway" was the largest ship in the world until 1955, as well as the first U.S. aircraft carrier too big to transit the Panama Canal.
 A revolutionary hull design, based on the planned "Montana"-class battleship , gave her enhanced protection compared to previous carriers.
 She operated for 47 years, during which time she saw action in the Vietnam War and served as the Persian Gulf flagship in 1991's Operation Desert Storm.
 Decommissioned in 1992, she is now a museum ship at the USS "Midway" Museum, in San Diego, California, and the only remaining U.S. aircraft carrier commissioned right after World War II ended that was not an "Essex"-class aircraft carrier .
The Yeosu–Suncheon rebellion, also known as the Yeo-Sun incident, was an October 1948 rebellion that took place in Yeosu, Suncheon, and surrounding towns, South Jeolla against the fledgling South Korean Syngman Rhee government largely cued by that government's suppression of the Jeju Uprising and refusal of Yeosu soldiers to help suppress the rebellion.
 In Yeosu, the rebelling South Korean soldiers seized weapons and took control of the town.
 The residents paraded through the town holding red flags.
 They restored the town people's committee, and tried and executed a number of police, officials, and landlords.
 The rebelling soldiers increased between 2,000 and 3,000, and massacred rights families and Christian youth.
 After one week the South Korean army overwhelmed the rebels.
 The matter was reviewed by the South Korean Truth and Reconciliation Commission, which found that government forces killed between 439 and 2000 area civilians.
 U.S. forces played a role in suppressing the rebellion: U.S. commanders planned and directed the military operations, U.S. military advisors accompanied all ROK units, and U.S. aircraft were used to transport troops.

Arsenic and Old Lace is a 1944 American dark comedy film directed by Frank Capra, starring Cary Grant, and based on Joseph Kesselring's play "Arsenic and Old Lace".
 The script adaptation was by Julius J. Epstein and Philip G. Epstein.
 Capra actually filmed the movie in 1941 because of star Cary Grant's availability, but it was not released until 1944, after the original stage version had finished its run on Broadway.
 The lead role of Mortimer Brewster was originally intended for Bob Hope, but he could not be released from his contract with Paramount.
 Capra had also approached Jack Benny and Ronald Reagan before learning that Grant would accept the role.
 Boris Karloff played Jonathan Brewster, who "looks like Karloff," on the Broadway stage, but he was unable to do the movie as well because he was still appearing in the play during filming, and Raymond Massey took his place.
 The film's supporting cast also features Priscilla Lane, Jack Carson, Edward Everett Horton and Peter Lorre.
