who is the known as the father of aviation
George Cayley In 1799 he set forth the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control.[2] [3] He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation."[1] He discovered and identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust.[4] Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also identified by Cayley.[5] He constructed the first flying model aeroplane and also diagrammed the elements of vertical flight.[6] He designed the first glider reliably reported to carry a human aloft. He correctly predicted that sustained flight would not occur until a lightweight engine was developed to provide adequate thrust and lift.[7] The Wright brothers acknowledged his importance to the development of aviation.[7]
Aviation in World War I At the start of the war, there was some debate over the usefulness of aircraft in warfare. Many senior officers, in particular, remained sceptical. However the initial campaigns of 1914 proved that cavalry could no longer provide the reconnaissance expected by their generals, in the face of the greatly increased firepower of twentieth century armies, and it was quickly realised that aircraft could at least locate the enemy, even if early air reconnaissance was hampered by the newness of the techniques involved. Early skepticism and low expectations quickly turned to unrealistic demands beyond the capabilities of the primitive aircraft available.[3]
