A forty-minute interview with Lewis, describing his experiences as a First World War pilot, was recorded by the BBC in 1963–64 and later made available online as part of the centenary commemorations of the war. In it, Lewis describes how on his first flight he had the most unusual experience of seeing 9-inch howitzer shells turning over in flight at 8,000 feet before descending to the target. He also described his most frightening experience of the war: a reconnaissance flight at 1,000 feet during the initial bombardment before the battle of the Somme. This entailed flying along the line of fire of shells. Close passing shells caused severe turbulence to his aircraft and a number of his friends were killed.
