Passage: Walt Disney engaged O'Malley to provide voices for animated films such as the Cockney coster in the "Supercalifragilisticexpialidocious" sequence in Mary Poppins (1964); Cyril Proudbottom, Winkie, and a policeman in The Adventures of Ichabod and Mr. Toad (1949); and the role of Colonel Hathi and the vulture Buzzie in The Jungle Book (1967). His voice can be heard in Alice in Wonderland (1951), in which he performs all the character voices in "The Walrus and the Carpenter" segment (besides Alice), including Tweedledum and Tweedledee, the Walrus, the Carpenter, and Mother Oyster.

Passage: He was present at the Battle of Manzikert in 1071, where he refused to join the fray; the battle proved to be a disastrous defeat for the Byzantines. Despite this treachery, he was kept in imperial service, where good generals were needed, and was sent into Asia Minor again with a force of 3,000 Franco-Norman heavy cavalry. There Roussel conquered some territory in Galatia and declared it an independent state in 1073, with himself as prince, following the example set by his fellow Normans in the Mezzogiorno. His capital was Ankara, now the capital of Turkey. He defeated the Caesar John Ducas and sacked Chrysopolis, near Constantinople. He even supported a usurper candidate, but by formally ceding lands that the Seljuk Turks had actually conquered, the emperor Michael VII persuaded the Seljuk warlord Tutush I to remove Roussel. However both Ducas and Roussel were defeated and captured by Turkish forces, fortunately for Roussel his wife was able to pay the ransom demanded by the Turks allowing Roussel to return to Amasea, where the population so loved him that he made himself undisputed governor. He was given up by the people through a ploy of Alexius Comnenus (1074), then a general, later an emperor.

Passage:  the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.
