Flying Minnows: Memoirs of a World War One fighter pilot, from training in Canada to the Front Line, 1917 - 1918

One particular anecdote worth noting is when flying his Bristol he was chased by several Fokker DR1 triplanes. In a shallow dive trying to escape them, when he notices his Observer has stopped firing, looking back to see why, he observes that his Observer has ran out of ammunition, and is hurling empty Lewis gun drum magazines, and anything else not fixed down at the chasing German pilots!
