The Chinese spy balloon that flew over the United States for days before being shot down could monitor communications signals, a U.S. official says. “High resolution imagery from U-2 flybys revealed that the high-altitude balloon was capable of conducting signals intelligence collection operations,” an official with the State Department, speaking on condition of anonymity, told The Epoch Times. “The high altitude balloon’s equipment was clearly for intelligence surveillance and inconsistent with the equipment onboard weather balloons. It had multiple antennas to include an array likely capable of collecting and geo-locating communications. It was equipped with solar panels large enough to produce the requisite power to operate multiple active intelligence collection sensors,” the official added.
