I recently posed the question on here as to weather you could take a motorbike helmet on a plane as carry on luggage, with a mixed response, well I'm here to tell you it's not a problem, as long, and get this, you don't actually wear it, it is then classed as light body armour and you will be refused entrance to the Airport, so there ya go people, tuck it under your wing and keep it off your melon and Bob's your Uncle.
