Aerospace engineering is the branch of engineering concerned with the design, construction and operation of aircraft and spacecraft, encompassing aeronautical engineering within Earth atmosphere and astronautical engineering beyond it. It matured as a distinct discipline in the first half of the twentieth century, driven first by heavier than air flight and then by rocketry and space exploration. Sir George Cayley, working in the late eighteenth and early nineteenth centuries, is credited as the first person to separate the forces of lift and drag that affect any atmospheric flight vehicle, and the compound term aerospace engineering was first defined in 1958 to treat the atmosphere and outer space as a single realm.
Facts
Core ConcernThe design and operation of aircraft and spacecraft. 1 Core PrincipleAerospace engineering treats aerodynamics, propulsion, avionics, materials science, structural analysis and manufacturing as one interacting system rather than separate disciplines, because a vehicle that must fly cannot optimize any one of them in isolation. 2 Disputed
Origin YearAeronautical engineering, a narrower predecessor concerned only with atmospheric flight, dates to the early 1900s; aerospace engineering, unifying atmospheric and space flight, dates to the late 1950s, alongside the founding of NASA in 1958. Connections

Did Gustave Whitehead achieve powered, controlled flight near Bridgeport, Connecticut in 1901-1902, before the Wright brothers' 1903 flights at Kitty Hawk?
Wikipedia's Gustave Whitehead article states "controversy surrounds published accounts and Whitehead's own claims that he flew a powered machine successfully several times in 1901 and 1902, predating the first flights by the Wright brothers in 1903." Connecticut's legislature officially recognized Whitehead as "Father of Connecticut Aviation" in 1968; North Carolina's General Assembly passed a 1985 resolution giving the claim "no credence." Mainstream aviation historians side with the Wright brothers, but the dispute remains live enough to have produced competing state resolutions decades apart.
What would resolve this Physical evidence (a surviving aircraft, verifiable photograph, or independently corroborated eyewitness record) of a genuinely powered, controlled 1901-1902 Whitehead flight, which mainstream aviation historians say does not exist.

Frequently Asked Questions
Why is aerospace engineering sometimes called rocket science, and how did its name change over time?
Aeronautical engineering was the field's original name, covering aircraft alone. As flight technology extended into outer space, the broader term aerospace engineering came into use to cover both the aeronautical and astronautical branches; the astronautics side in particular is often called rocket science in everyday speech.
