My habit of attacking Huns dangling from their parachutes led to many arguments in the mess. Some officers, of the Eton and Sandhurst type, thought it was 'unsportsmanlike' to do it. Never having been to a public school, I was unhampered by such considerations of form. I just pointed out that there was a bloody war on, and that I intended to avenge my pals.
It is wonderful how cheered a pilot becomes after he shoots down his first machine; his morale increases by at least 100 percent.
