'''Aircraft''' are machines that fly up into the air. The earliest aircraft were [[kite]]s and [[hot air balloon]]s.
Many attempts were made to achieve heavier-than-air flight towards the end of the 19th century, in Europe and America. However, even when engines became powerful enough to pull an aircraft through the sky, the problem was control. The [[Wright Brothers]] solved this problem by realizing that twisting the wings would control the ''[[roll]]'' of the aircraft.
