Did US Air Force Shoot Down a Party Balloon?

President Biden revealed that the flying objects shot down by the U.S. Air Force were probably harmless. Now, the Northern Illinois Bottlecap Balloon Brigade say they believe their $12 balloon was shot down over Alaska by a $400,000 missile. They track their balloons floating around the world with solar-powered GPS technology. The balloon shot down over Alaska was apparently named K9YO-15, which disappeared on February 10th.
