"Over the decades, a number of spacecraft have been proposed for spaceliner passenger travel. Somewhat analogous to travel by airliner after the middle of the 20th century, these vehicles are proposed to transport large numbers of passengers to destinations in space, or on Earth via suborbital spaceflights. To date, none of these concepts have been built, although a few vehicles that carry fewer than 10 persons are currently in the test flight phase of their development process.[citation needed]
