First, the US isn’t going to shoot down small balloons like this one after possibly shooting 3 civilian ones. They will only react to larger ones. Second, what kind of useful sensors will they put on small balloon? I guess might be able to fit camera, even long lens, in the 12lb payload of small balloon but doubt get much useful info. Third, we may see a movement to put transponders in larger balloons. Requiring ADS-B would be reasonable.
