Origin
The term is a calque of the French *ballon d’essai*, literally a "trial balloon." The practice involved releasing a small, unmanned balloon into the sky to determine the direction and tendency of the winds in the upper air before a manned ascent was attempted in a larger vessel. By monitoring the drift of the smaller craft, aeronauts could assess whether the conditions were suitable for a more significant commitment.
The figurative transition from meteorology to public affairs occurred by the late 19th century. Just as the physical *ballon d’essai* tested the atmosphere, the metaphorical version serves as a prospective action to test public acceptance. It remains a method of releasing a small amount of information to gauge the strength of the prevailing political winds before an actual policy is launched.
