Chinese spy balloon infiltrates sensitive U.S. military sites.

The Chinese spy balloon that flew over the U.S. was able to gather intelligence from several sensitive American military sites, despite the Biden administration's efforts to block it from doing so. China was able to control the balloon so it could make multiple passes over some of the sites and transmit the information it collected back to Beijing in real time. The intelligence China collected was mostly from electronic signals, which can be picked up from weapons systems or include communications from base personnel, rather than images.
