The V-sign
Two finger salute
There is an alternative name for the V-sign stemming from the myth that it came about during the Battle Of Agincourt. It can also be known as flicking an "Archers Salute" or just "Archers" as in "He just flicked me an Archers!"
Engine blueprints
Winston Churchill considered the Rolls-Royce Merlin engine used in Spitfires such an indispensible part of Britain's air defences that in 1940, he ordered a set of blueprints to be sent to the US in case the UK was invaded by Nazi Germany.
