The Cloistered Order of Conclaved Knights of Sophisticracy, more commonly known as the Knights of the Clock, was an interracial homophile social club based in Los Angeles, California.
 The Knights were founded by Merton Bird, an African-American man, and W. Dorr Legg, his white lover.
 Sources differ as to the founding date of the organization, variously citing it as 1949, 1950, and 1951.
 Regardless of the exact date, the Knights was one of the earliest gay organizations in the United States, with only the Society for Human Rights (established 1924), the Veterans Benevolent Association (established 1945) and possibly the Mattachine Society (established 1950) pre-dating it.
The Tolkāppiyam (Tamil: தொல்காப்பியம் ) is a work on the grammar of the Tamil language and the earliest extant work of Tamil literature and linguistics.
 It is written in the form of "noorpaa" or short formulaic compositions and comprises three books – the "Ezhuttadikaram", the "Solladikaram" and the "Poruladikaram".
 Each of these books is further divided into nine chapters each.
 While the exact date of the work is not known, based on linguistic and other evidence, it has been dated variously between the third century BCE and the 10th century CE.
 Some modern scholars prefer to date it not as a single entity but in parts or layers.
 There is also no firm evidence to assign the authorship of this treatise to any one author.

 The Boeing 737-200 was flying from Hilo, Hawaii to Honolulu, Hawaii, when it experienced rapid decompression when a section of the fuselage was torn away.

Wanderers Football Club is a Senior rugby union club based in Dublin, Ireland, playing in Division 2B of the All-Ireland League.
 It is one of the oldest rugby clubs in Ireland, however its exact date of foundation is open to question.
 In 1860 a team by the name of Wanderers played against Dublin University.
 However the current team gives its foundation date as 1870.
 While the link between the two teams is unclear, they both seem to have been founded by former Dublin University players.
 In 1879 Wanderers were among the founding members of the Irish Rugby Football Union.
 They have also regularly provided international players for Ireland, including five captains.
 In 1959, Ronnie Dawson also went on to captain the British and Irish Lions.
 They have also provided one captain each for both England and Australia.

 There was one fatality, flight attendant Clarabelle "C.B." Lansing, who was ejected from the airplane.
 Another 65 passengers and crew were injured.
 The safe landing of the aircraft despite the substantial damage inflicted by the decompression established Aloha Airlines Flight 243 as a significant event in the history of aviation, with far-reaching effects on aviation safety policies and procedures.
