The Pentagon has released details on an unidentified flying object shot down in Canadian airspace, which was a "small, metallic balloon with a tethered payload below it." China has reported that high-altitude balloons belonging to the United States had flown over its airspace without permission more than 10 times since early last year. Lawmakers are pressing the Biden administration for more information on the objects and if they posed any threat to the United States or its allies.
