Aerospace engineering has its origins in the late 19th to early 20th centuries, with significant contributions from pioneers like Sir George Cayley. The field encompasses both aeronautics and astronautics, focusing on the design and manufacturing of vehicles for air and space, primarily for governmental purposes. Aerospace engineering includes two main branches: aeronautical engineering for aircraft in the atmosphere and astronautical engineering for spacecraft.

2.  The origin of aerospace engineering can be traced back
to the aviation pioneers around the late 19th to early 20th
centuries, although the work of Sir George Cayley has
recently been dated as being from the last decade of the
18th to mid-19th century.
 Aerospace comprises the atmosphere of Earth and
surrounding space.
 Typically, aerospace industries combine aeronautics and
astronautics to research, design, manufacture, operate, or
maintain vehicles moving through air and space.
 Aerospace is a very diverse field, with a multitude of
commercial, industrial and military applications.

3. Aerospace manufacturing is a
high technology industry that
produces "aircraft, guided
missiles, space vehicles, aircraft
engines, propulsion units, and
related parts". Most of the
industry is geared toward
governmental work. For each
Original Equipment
Manufacturer (OEM), the US
government has assigned a CAGE
code. These codes help to identify
each manufacturer, repair
facilities, and other critical
aftermarket vendors in the
aerospace industry.

5. Aerospace engineering is the
primary branch of engineering
concerned with the
research, design, development,
construction, testing, science
and technology of aircraft and
spacecraft. It is divided into two
major and overlapping
branches: aeronautical
engineering and astronautical
engineering. The former deals
with aircraft that operate in
Earth's atmosphere, and the
