It was a strange few days. The big multi-bus-sized balloon was ignored for several days while it loitered over sensitive areas, then, suddenly, they turned up the sensitivity and may have shot down hobbyist balloons. It's as if NORAD etc., were caught unprepared and had no idea which way to go on this and were waiting for a decision higher up and then went bananas.

Still there's something incongruous, it was claimed the USAF did flybys before shooting them down to ensure the balloons were not misidentified manned balloons.
