UPDATE 5:21 p.m. ET: Washington Post reports US military aircraft shot down the craft they were trailing over northern Canada.
CNN reports that NORAD is currently tracking at least one more likely Chinese spy balloon that is floating at high altitude over northern Canada. CNN says military aircraft (they do not specify if they are American or Canadian or both) are currently tracking one object, just a day after the US military shot down an unknown object that had entered US airspace over Alaska.
