Pentagon continues to track suspect Chinese surveillance balloon drifting over the U.S.

The suspected surveillance balloon is believed to be somewhere over the St. Louis area, as of Feb. 3. Chinese officials say it is a civilian aircraft used for weather research that had accidentally blown off course, but U.S. officials say they believe it is a spy balloon. Meanwhile, people are wondering why the balloon has not been shot down yet. FOX 10's Ellen McNamara reports.
