The practice, sport, or art of flying in hot air balloons; also, exaggerated or inflated talk.
From 'balloon' plus the suffix '-ery' (from Old French), which denotes an activity, art, or collection related to the root word.
Before airplanes existed, 'balloonery' was the most thrilling way to see the world from above—the sport connected astronomy, meteorology, and adventure in one weightless package.
