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.

 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.

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".

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.”
