 When the AI team arrived on 5 November 1939, they found themselves being housed in a disused hangar with no office space. A small amount of relief was found by using abandoned Heyford wings as partitions, but this proved largely useless as the weather turned cold. As the main doors of the hangar were normally left open during the day, it was often too cold to hold a screwdriver. Bowen complained that the conditions "would have produced a riot in a prison farm."
