The wings change shape as they beat up and down. They are broad and extended on the down stroke, but tucked in tight on the upstroke.
The early gliders led the way for the development of the aeroplane. Wilbur and Orville Wright read about many experiments with gliders and followed their progress to be the first to create the first succesful flying machine.
The human body is too heavy and does not have the muscles needed for flight.
Long wings are more efficient than short wings, but much harder to flap. Birds with long wings are usually soaring birds. Short-winged birds have less stamina, but can build up speed very quickly.
The wings of an aeroplane are a a special shape, called an aerofoil. The top of the wing is straight.
In Ancient Greece the inventor Daedalus was said to have been imprisoned along with his son on the island of Crete. Daedalus built wings of feathers and wax so that they could fly to freedom across the sea. But icarus was so fascinated by the power of his wings that he grew reckless and flew too close to the sun, melting the wax of his wings. He crashed into the sea and perished.
The glider was created first before the balloon. Humans first noticed the wings of birds and how they used their wings to glide. Leonardo da Vinci (1452-1519) was one of the world's great thinkers and first serious student of the science of aeronautics. Had it not been for the breadth of his genius and the resulting variety of his interests, he might have designed the first man-carrying glider.
In the 1700's, the French brothers Joseph and Etienne Montgolfier designed the first successful flying craft, a hot air balloon.
Concorde can fly passengers to their destination in little more than half the time taken by other airliners.
Rather, John Duigan was most well known as our first pioneer in the area of powered flight. He was the first person to build and fly a powered plane in Australia.
However, it was in November 1935, that Kingsford Smith set out from Allahabad in India on the second leg of a flight from England to Australia.
During this flight, it is believed that he probably crashed near the coast of Burma, and that he was killed in the crash.
