Wonder wings
A gyroplane (a flying machine balanced and supported by rapidly rotating horizontal or slightly inclined blades) said to be capable of flying non-stop around the world at 800 kmph has been developed in the US. Texas-based Jay Carter says his Cartercopter, fitted with two rotors and a modified racing- car engine will be able to take off vertically and accelerate to 80 kmph within three seconds. The Cartercopter looks like a cross between an aircraft and a helicopter, with large top rotors and small wings which double as fuel tanks and a plane-like tail assemble.
