These difficulties, solved over time by determined engineers and inventors, made the progress of vertical flight seem slow compared to that of conventional flight, for the first useful helicopters did not appear until the early 1940s. But vertical flight is also the most demanding challenge in flying, requiring more sophistication in structure, power, and control than conventional fixed-wing aircraft. It is the most logical form of flight, dispensing as it does with large landing fields located far from city centres and the inevitable intervening modes of travel-automobile, subway, bus-that flight in conventional aircraft usually requires. The idea of taking off vertically, making the transition to horizontal flight to the destination, and landing vertically has been for centuries the dream of inventors. Other vertical-flight craft include autogiros, convertiplanes, and V/STOL aircraft of a number of configurations.
Helicopter, aircraft with one or more power-driven horizontal propellers or rotors that enable it to take off and land vertically, to move in any direction, or to remain stationary in the air. It wasn't until the 1930s that the technology advanced enough to allow helicopter flights across substantial distances. The first helicopter-like, motorized aircraft that could rise above the ground (often only a foot or two, and for only seconds) were flown in 1907.
