Wokka
Boeing CH-47 Chinook helicopter, named for the chop of its twin rotors.
Definitions
British forces nickname for the Chinook, straight-up onomatopoeia for the unmistakable 'wokka-wokka-wokka' beat the twin tandem rotors make as they slap the air. If you've been near one you know the sound before you see it. Universal across the British Army and RAF — pilots, crew, and the squaddies riding in the back all use it.
