We begin with the scare in the paper a southwest flight landing at the wrong airport in missouri. Coming within feet of going over a -- the cliff -- the edge of a cliff. Abc's alex perez is at midway airport in chicago where the flight originated. Good morning, alex. Many unanswered questions this morning. The passengers said they knew something went wrong when they felt the pilot slam on the breaks. We kind of stopped abruptly. Reporter: A flight packed with 124 passengers took off from chicago's midway airport and was supposed to land at branson airport in missouri. Instead, it landed eight miles away at a tane count airport. The runway so short it reportedly forced the pilot to slam on the brake, coming to a halt just 500 feet from a road way. Just moments after the landing, the pilot tries to calm passengers' nerves. People know we're here. And we'll be taking care of you just as soon as we can. Thanks again for your patience.
