observation balloon
Tethered sky watcher
An observation balloon is a tethered balloon used for military reconnaissance or artillery spotting.
Unlike free-flying balloons, it remains anchored to the ground by cables, allowing observers in its basket to survey enemy positions and report back.
Observation balloons saw heavy use in World War I, where they became targets for fighter aircraft.
