Very little is known about Kellaway's early life, apart from the fact that he was cared for by a nanny, who advised him to disguise mistakes in a drawing by turning them into a cloud, or a tree.
World War OneEdit
Kellaway served as a fighter pilot with the Royal Flying Corps.
World War TwoEdit
Kellaway first appears in the flashback to The Ram's return from sick leave in the third week of August, when Ramsey orders Kellaway to recall all the pilots from leave - a process that takes three days. 
While the pilots were taking part in a cross country run, Kellaway discussed the First World War with the sergeant of police,  before organising a rugby match with the Fairey Battle squadron that shared the airfield, and supervising the digging of slit trenches near dispersal, while The Ram led the pilots on a battle climb.[N 2]

By 1942, Kellaway and Hornet Squadron were in North Africa
