Is your airplane physically on fire?</s>PILOT: Not fire, but part of it is missing. They said there's a hole and someone went out.</s>AIR TRAFFIC CONTROL: I'm sorry. You said there is a hole and somebody went out? 1380. It doesn't matter. We'll work it out there.</s>BOLDUAN: Investigators now say the failed engine show signs of metal fatigue. Much to learn in what happened here. CNN's Polo Sandoval is in Philadelphia with much more of the details. Polo, what are you hearing there?</s>POLO SANDOVAL, CNN CORRESPONDENT: Mainly about the pilot, Kate, Captain Tammy Joe Schultz, a woman who passengers said had nerves of steel yesterday when she and her other colleague managed to land that plane safely here in Philadelphia. We do, after all, know why she sounded so cool, calm, collected in that recording that you just played. She was, after all, according to the Navy one of their first female fighter pilots and spent time in California, training future pilots, as well. And what happened 24 hours ago when she heard that the 737 she was flying with all those people onboard literally had a hole in the plane. We now know that there was a woman that was at least partially ejected at one point as you're about to hear from one passenger, it took in their own words, several minutes to finally be able to pull that woman back into the cabin.
