The origin of aerospace engineering can be traced backto the aviation pioneers around the late 19th to early 20thcenturies, although the work of Sir George Cayley hasrecently been dated as being from the last decade of the18th to mid-19th century. Aerospace comprises the atmosphere of Earth andsurrounding space. Typically, aerospace industries combine aeronautics andastronautics to research, design, manufacture, operate, ormaintain vehicles moving through air and space. Aerospace is a very diverse field, with a multitude ofcommercial, industrial and military applications.
Aerospace manufacturing is ahigh technology industry thatproduces "aircraft, guidedmissiles, space vehicles, aircraftengines, propulsion units, andrelated parts". Most of theindustry is geared towardgovernmental work. For eachOriginal EquipmentManufacturer (OEM), the USgovernment has assigned a CAGEcode. These codes help to identifyeach manufacturer, repairfacilities, and other criticalaftermarket vendors in theaerospace industry.
Aerospace engineering is theprimary branch of engineeringconcerned with theresearch, design, development,construction, testing, scienceand technology of aircraft andspacecraft. It is divided into twomajor and overlappingbranches: aeronauticalengineering and astronauticalengineering. The former dealswith aircraft that operate inEarths atmosphere, and the
