A Girl Scout troop was swimming at a state park when a 14 foot alligator appeared. The troop leaders jumped into action to get the kids out of the water - with good reason, because witnesses say the gator was in attack mode. And today NASA released the results of its study of UFOs, and it comes as images of purported aliens are going viral. You've probably seen them pop up on social media...but a number of scientists say it's all a hoax. Plus, a father and daughter were about to land in a small plane when they crashed. Despite being terribly injured, they survived. Now they're talking with Les Trent about their ordeal. And it's being called the world's most expensive sweater. The black sheep pullover Princess Diana wore before her marriage to Prince Charles sold at auction today for 1.1 million dollars!
