Editing Flight (section)

=== Ballistic ===
{{Main|Ballistics}}

==== Atmospheric ====
Some things generate little or no lift and move only or mostly under the action of momentum, gravity, air drag and in some cases thrust. This is termed ''ballistic flight''. Examples include [[ball]]s, [[archery|arrows]], [[bullet]]s, [[firework]]s etc.

==== Spaceflight ====
{{Main|Spaceflight}}
Essentially an extreme form of ballistic flight, spaceflight is the use of [[space technology]] to achieve the flight of [[spacecraft]] into and through [[outer space]]. Examples include [[ballistic missile]]s, [[orbital spaceflight]], etc.

Spaceflight is used in [[space exploration]], and also in commercial activities like [[space tourism]] and [[telecommunications satellite|satellite telecommunications]]. Additional non-commercial uses of spaceflight include [[Space observatory|space observatories]], [[reconnaissance satellite]]s and other [[Earth observation satellite]]s.

A spaceflight typically begins with a [[rocket launch]], which provides the initial thrust to overcome the force of [[gravity]] and propels the spacecraft from the surface of the Earth.<ref>{{Cite book| url=https://books.google.com/books?id=kjVGAAAAYAAJ&q=A+spaceflight+typically+begins+with+a+rocket+launch,+which+provides+the+initial+thrust+to+overcome+the+force+of+gravity | title=Astronautics: A Historical Perspective of Mankind's Efforts to Conquer the Cosmos | last=Spitzmiller | first=Ted | date=2007 | page=467 | publisher=Apogee Books | isbn=9781894959667 | language=en}}</ref> Once in space, the motion of a spacecraft—both when unpropelled and when under propulsion—is covered by the area of study called [[astrodynamics]]. Some spacecraft remain in space indefinitely, some disintegrate during [[atmospheric reentry]], and others reach a planetary or lunar surface for landing or impact.

==== Solid-state propulsion ====
In 2018, researchers at [[Massachusetts Institute of Technology]] (MIT) managed to fly an aeroplane with no moving parts, powered by an "[[ion]]ic wind" also known as electroaerodynamic thrust.<ref>{{cite news<!--|authors=Haofeng Xu, Yiou He, Kieran L.
