Early attempts to fly were continuously made by trying to imitate the birds using flapping wings. But human-arms are too weak to flap wings for long so machines were made to aid arms or legs to perform flapping. In this video you will notice how immense the desire to fly actually used to be during those early days, which made them try and try and keep on trying. Though its also obvious from this video that most attempts totally failed, until the iconic first flight of the Wright brothers in year 1903. Some of these flight attempts and landings in this video are quite funny.
