Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipTwo, and uncrewed ones, such as ICBMs and sounding rockets.
Following the definition that a civilian is someone who is not part of their country's armed forces (not in active duty; former service or reservist status is not considered being part of armed forces), [1] these are suborbital space flights (spaceflight according to US 50 mile space boundary definition) with a fully civilian crew:
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth , it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around 80 kilometers (50 mi); this is the boundary of ...
Sub-orbital space flight is any space launch that reaches space without making a full orbit around the planet, and requires a maximum speed of around 1 km/s to reach space, and up to 7 km/s for longer distance such as an intercontinental space flight. An example of a sub-orbital flight would be a ballistic missile, or future tourist flight such ...
The latter altitude, achieved twice by Walker, exceeds the modern international definition of the boundary of space. The United States Federal Aviation Administration also recognizes this line as a space boundary: [22] Suborbital Flight: Suborbital spaceflight occurs when a spacecraft reaches space but its velocity is such that it cannot ...

Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
