Eddie Rickenbacker,
Fighting the Flying Circus — Chapter 30
(1919)
“ It was in a decidedly bad place for an attack, but Cook unhesitatingly stuck down his nose and began firing as he dived. About twenty or thirty shots left his guns — and then both jammed. With a string of burning words Cookie turned around as he zoomed up over the balloon and hurled at it the small hammer or tool used by pilots for clearing gun-jams. He was so enraged over his bad luck that he did not even wait for Crocker to overtake him, but made straight for home, climbed out of his machine and marched into the Armorers' office, mad as a hornet. ”
