To commemorate the centenary of first flight, UNPA is issuing for the first time a tête-bêche stamp in the denominations of 23 cents and 70 cents. A tête-bêche stamp is a pair of stamps connected together with one right side up, the other upside down. When the two stamps are combined, a full rotation of a propeller in motion can be seen.
The Wright Brothers and the First Flight – Orville Wright and his brother Wilbur, owners of a bicycle-making firm, began to experiment with heavier-than-air flight in 1896. The world’s first sustained powered flight was made by Orville on 17 December 1903 near Kill Devil Hill, Kitty Hawk, North Carolina. That first flight, made in the 12-horsepower, chain-driven Flyer I, lasted for about 12 seconds. It covered a distance of 36.5 metres (120 feet) at an airspeed of 48 kilometres/ hour (30 miles/hour), a ground speed of 10.9 kilometres/hour (6.8 miles/hour) and an altitude of 2.5-3.5 metres (8-12 feet)
