The antonyms for "putting flight" are essentially the opposite actions such as "grounding," "landing," and "stopping." When you ground yourself or something, you are keeping it firmly in place and preventing it from taking off or flying. Landing is the act of touching down after being airborne whereas stopping refers to coming to a complete stop. All three of these actions imply a loss of momentum and indicate a return to a stationary or grounded state. Often, the antonyms of "putting flight" are associated with a reduction in speed, energy, or excitement, resulting in a less dynamic, less lively situation.
