Transcript for Investigation underway behind deadly California plane crash
New developments in that deadly California plane crash. This morning we're learning more about the pilot as new video emerges showing that plane falling from the sky. Our chief national correspondent Matt Gutman remains on the scene. Good morning, Matt. Reporter: Good morning, robin. We know now from investigators that it was a wing from that plane full of fuel after takeoff that slammed into that house causing that massive fireball and, of course, claiming the lives of four people inside. Now investigators are turning to eyewitness testimony and new video to figure out why that plane broke up over this neighborhood. This video captures the twin engine Cessna free-falling before bursting into flames showering this southern California neighborhood with blazing debris. Witness reports say that they saw the airplane coming out of a cloud at a very high speed before parts of the airplane such as tail and the subsequent wings started to break off. Reporter: The pilot now identified as 75-year-old Anton Joan pestini, killed along with four inside the home who gather there had to watch the super bowl. Debris littering a four-block area, at least 15 houses pelted with parts of the aircraft, on Monday, investigators began the arduous task of gathering up the parts of the plane. You can see the flatbed has been going around the neighborhood picking up pieces of debris. Right there is the nose of the plane. This appears to be part of a wing. I think a tail is in there. Investigators tell us that the scale of the debris field is enormous. Some residents running for cover as the debris fell from the sky. Saw part of the airplane come down and saw the wick fall down as well. Heard a loud crash. Reporter: The wing which houses a fuel tank smash nothing this home and bursting into flames. Now, all those plane parts, the NTSB will take them to a warehouse in Phoenix and literally reconstruct the plane. I'm told another factor they are also going to examine is the weather. It has been raining here for days and it is feared that that pilot became disoriented flying out of a cloud and lost control of the plane. George. Okay, Matt, thanks very much.
