Air Marshal Sir Richard Williams, (3 August 18907 February 1980) is widely regarded as the "father" of the Royal Australian Air Force (RAAF).
 He was the first military pilot trained in Australia, and went on to command Australian and British fighter units in World War I.
 A proponent for air power independent of other branches of the armed services, Williams played a leading role in the establishment of the RAAF and became its first Chief of the Air Staff (CAS) in 1922.
 He served as CAS for thirteen years over three terms, longer than any other officer.
Marshal of the Royal Air Force Sir John Cotesworth Slessor, {'1': ", '2': ", '3': ", '4': "} (3 June 1897 – 12 July 1979), sometimes known as Jack Slessor, was a senior commander in the Royal Air Force (RAF), serving as Chief of the Air Staff from 1950 to 1952.
 As a pilot in the Royal Flying Corps during the First World War, he saw action with No. 17 Squadron in the Middle East, earning the Military Cross, and with No. 5 Squadron on the Western Front, where he was awarded the Belgian Croix de Guerre.
 Between the wars he commanded No. 4 Squadron in England, and No. 3 (Indian) Wing, earning the Distinguished Service Order for operations with the latter in Waziristan.
 In 1936, he published "Air Power and Armies", which examined the use of air power against targets on and behind the battlefield.
Air Vice Marshal Henry Neilson Wrigley, CBE, DFC, AFC (21 April 1892 – 14 September 1987) was a senior commander in the Royal Australian Air Force (RAAF).
 A pioneering flyer and aviation scholar, he piloted the first trans-Australia flight from Melbourne to Darwin in 1919, and afterwards laid the groundwork for the RAAF's air power doctrine.
 During World War I, Wrigley joined the Australian Flying Corps and saw combat with No. 3 Squadron on the Western Front, earning the Distinguished Flying Cross; he later commanded the unit and published a history of its wartime exploits.
 He was awarded the Air Force Cross for his 1919 cross-country flight.
Victory Through Air Power is a 1943 American Technicolor animated documentary feature film produced by Walt Disney Productions and released by United Artists on July 17, 1943.
 It is based on the 1942 book "Victory Through Air Power" by Alexander P. de Seversky.
 De Seversky appeared in the film, an unusual departure from the Disney animated feature films of the time.
The Battle of Majorca, also known as the Majorca Landings, was an amphibious landing of Republican forces early in the Spanish Civil War aimed at driving the Nationalists from Majorca and reclaiming the island for the Republic.
 After some initial tactical success, the expedition, commanded by Captain Alberto Bayo, ended in failure when the Nationalists counterattacked with ground troops and massively superior air power and drove the Republicans into the sea.
 So confident were the Republicans in their prediction of victory they optimistically called the operation ""la reconquista de Mallorca"" - "the reconquest of Majorca".
Frozen is a 2013 American 3D computer-animated musical fantasy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures.
 It is the 53rd Disney animated feature film.
 Inspired by Hans Christian Andersen's fairy tale "The Snow Queen", the film tells the story of a fearless princess who sets off on a journey alongside a rugged iceman, his loyal pet reindeer, and a naïve snowman to find her estranged sister, whose icy powers have inadvertently trapped the kingdom in eternal winter.
Praporshik Aleksandr Mikhailovich Pishvanov was a World War I flying ace credited with five aerial victories.
 After an unsuccessful fight against the Communist takeover of Russia, he became an American citizen in 1928.
 His engineering skills were useful to both Sikorsky Aviation and to Seversky Aircraft Corporation from 1926 onwards.
 In 1942, he helped Walt Disney produce Victory Through Air Power to support the American war effort.
 Pishvanov's interest in aviation ended only with his death in New York City in 1964.
Victory Through Air Power is a 1942 non-fiction book by Alexander P. de Seversky.
 It was made into a 1943 Walt Disney animated feature film of the same name.

Portraits Is the debut studio album from British metalcore band Bury Tomorrow.
 The album was released first in the United Kingdom on Basick Records on 12 October 2009.
 Adam Jackson has stated it was named Portraits for two reasons: "Firstly, the title track is based on the story of Dorian Gray by Oscar Wilde, a cautionary tale of the beauty and frailty of life.
 Secondly, Portraits depicts a person or character frozen in time as they were at a given moment.
 This is how we see this album – it's a reflection of our tastes, loves, hates, losses and gains.
 It's a memory in musical form, the first glimpse of the picture that is Bury Tomorrow.”
