Valentine Browne, 1st Earl of Kenmare (January 1754 – 3 October 1812) was the Seventh Baronet Browne.
 He was created First Baron Castlerosse and First Viscount Kenmare on 12 February 1798, with the earlier peerages not being recognised.
 He was created First Earl of Kenmare on 3 January 1801.
World UFO Day is an awareness day for people to gather together and watch the skies for unidentified flying objects.
 The day is celebrated by some on June 24, and others on July 2.
 June 24 is the date that aviator Kenneth Arnold reported what is generally considered to be the first widely reported unidentified flying object sighting in the United States, while July 2 commemorates the supposed UFO crash in the 1947 Roswell UFO Incident.
Edward J. Ruppelt (July 17, 1923 – September 15, 1960) was a United States Air Force officer probably best known for his involvement in Project Blue Book, a formal governmental study of unidentified flying objects.
 He is generally credited with coining the term "unidentified flying object", to replace the terms "flying saucer" and "flying disk" - which had become widely known - because the military thought them to be "misleading when applied to objects of every conceivable shape and performance.
 For this reason the military prefers the more general, if less colorful, name: unidentified flying objects.
 UFO (pronounced Yoo-foe) for short."
A flying saucer (also referred to as a flying disc) is a descriptive term for a supposed type of flying craft having a disc or saucer-shaped body, commonly used generically to refer to an anomalous flying object.
 The term was coined in 1930 but has generally been supplanted since 1952 by the United States Air Force term unidentified flying objects or UFO's.
 Early reported sightings of unknown "flying saucers" usually described them as silver or metallic, sometimes reported as covered with navigation lights or surrounded with a glowing light, hovering or moving rapidly, either alone or in tight formations with other similar craft, and exhibiting high maneuverability.
The Robertson Panel was a scientific committee which met in January 1953 headed by Howard P. Robertson.
 The Panel arose from a recommendation to the Intelligence Advisory Committee (IAC) in December 1952 from a Central Intelligence Agency (CIA) review of the U.S. Air Force investigation into unidentified flying objects, Project Blue Book.
 The CIA review itself was in response to widespread reports of unidentified flying objects, especially in the Washington, D.C. area during the summer of 1952.
The BFG is a 2016 American fantasy adventure film directed and co-produced by Steven Spielberg, written by Melissa Mathison and based on the 1982 novel of the same name by Roald Dahl.
 The film stars Mark Rylance, Ruby Barnhill, Penelope Wilton, Jemaine Clement, Rebecca Hall, Rafe Spall and Bill Hader.
 In the film, an orphan human girl befriends a benevolent giant, dubbed the "Big Friendly Giant", who takes her to Giant Country, where they attempt to stop the man-eating giants that are invading the human world.
The Condon Committee was the informal name of the University of Colorado UFO Project, a group funded by the United States Air Force from 1966 to 1968 at the University of Colorado to study unidentified flying objects under the direction of physicist Edward Condon.
 The result of its work, formally titled Scientific Study of Unidentified Flying Objects, and known as the Condon Report, appeared in 1968.
Mystery airships or phantom airships are a class of unidentified flying objects best known from a series of newspaper reports originating in the western United States and spreading east during late 1896 and early 1897.
 According to researcher Jerome Clark, airship sightings were reported worldwide during the 1880s and 1890s.
 Mystery airship reports are seen as a cultural predecessor to modern claims of extraterrestrial-piloted flying saucer-style UFOs.
 Typical airship reports involved unidentified lights, but more detailed accounts reported ships comparable to a dirigible.
 Reports of the alleged crewmen and pilots usually described them as human-looking, although sometimes the crew claimed to be from Mars.
 It was popularly believed that the mystery airships were the product of some inventor of genius who was not ready to make knowledge of his creation public.
 For example, Thomas Edison was so widely speculated to be the mind behind the alleged airships that in 1897 he "was forced to issue a strongly worded statement" denying his responsibility.
Unidentified Flying Oddball (also known as The Spaceman and King Arthur and A Spaceman in King Arthur's Court) is a 1979 film adaptation of Mark Twain's "A Connecticut Yankee in King Arthur's Court", directed by Russ Mayberry and produced by Walt Disney Productions.
 Subsequently re-released in the United States under the titles "The Spaceman and King Arthur" and "A Spaceman in King Arthur’s Court", the film starred Dennis Dugan as NASA employee Tom Trimble who unintentionally travels back in time with his look-alike android Hermes.
 Trimble’s NASA spacecraft travels faster than the speed of light, landing him and the android near King Arthur’s Camelot, where – with the aid of their 20th-century technology – they must defeat a plot by the evil Sir Mordred and Merlin to oust King Arthur from the throne.
A Kid in King Arthur's Court is a 1995 Disney family film directed by Michael Gottlieb.
 It is based on the famous Mark Twain novel "A Connecticut Yankee in King Arthur's Court" (previously filmed by Disney as "Unidentified Flying Oddball" in 1978 in which Ron Moody also played Merlin), transplanted into the twentieth century.
 Trimark later released a sequel, "A Kid in Aladdin's Palace", in 1998, but without Disney's involvement.
 Since Trimark's dissolution, the sequel is now distributed by Lions Gate Entertainment.
