Some flying facts

? The Frisbee is named after the Frisbie Pie Company of Bridgeport, Connecticut, whose tins 19th century Yale students used as toys.

? Argument rages over whether the first "Frisbee" was a pie tin or a cookie tin lid.

? After the Second World War, inventor Fred Morrison made a plastic version to cash in on the national obsession with flying saucers.

? In 1957 the Wham-O company began producing it commercially, but it was plagued by wobbly flight and outsold by Wham-O's Hula Hoop.

? Wham-O registered the name Frisbee in 1959.

? In 1964 Wham-O's Ed Headrick devised aerodynamic ridges to improve the flight and a national craze took off.

? Headrick was granted the patent in 1967 for the modern Frisbee, then called the "Flying Saucer".
