It's what the whole nation is talking about. A balloon from China floating over U.S. airspace. The Pentagon says it's on a spying mission flying directly over missile silos in Montana leading to calls to shoot it out of the sky. And we may not have even known it was there if not for the eagle eyes of this guy - one of the first people to spot the balloon. He spoke with Steven Fabian. And the record cold weather is wreaking havoc from Montana to Maine. And the word is, if you don’t have to go outside…stay indoors. And thanks to the deep freeze…there's a very rare weather phenomenon happening in some places. It's called “a frost quake.” Les Trent explains what it is. Plus, he was a doctor who took an afternoon bike ride on California’s Pacific Coast Highway. Now the emergency room physician is dead. Cops say a motorist intentionally slammed into him from behind and then stabbed him to death. The sheriff's department says they don't believe the two men knew each other...so was this a different kind of road rage? The driver has pleaded not guilty. And we've told you about the young model who was terribly disfigured after a pit bull ripped off her upper lip. Now, after a half a dozen surgeries and a whole lot determination...she's ready to show off her new smile.
