The above experiments search for a fifth force that is, like gravity, independent of the composition of an object, so all objects experience the force in proportion to their masses. Forces that depend on the composition of an object can be very sensitively tested by torsion balance experiments of a type invented by Loránd Eötvös.
Aerodynamics work throughout the 19th century sought to achieve heavier-than-air flight. George Cayley developed the concept of the modern fixed-wing aircraft in 1799, and in doing so identified the four fundamental forces of flight - lift, thrust, drag, and weight. The development of reasonable predictions of the thrust needed to power flight ...

Future Vertical Lift (FVL) is a plan [1] to develop a family of military helicopters for the United States Armed Forces.Five different sizes of aircraft are to be developed, sharing common hardware such as sensors, avionics, engines, and countermeasures. [2]
The last flight took place on 19 [O.S. 7 July] 1874, Willemot flying together with Colonel Nicolae Haralambie, Ion Ghica and a third person.
