SUMMARY
A shuttle does not need to be in a circular orbit to achieve apparent weightlessness; any freefall trajectory, including elliptical or parabolic orbits, results in the same effect. Both the astronauts and the shuttle experience weightlessness due to falling at the same acceleration. The design of the Shuttle did not specifically aim for apparent weightlessness; it was merely a byproduct of maintaining a stable orbit.
