Transcript for Out-Of-Control Car Smashes Into LAX Terminal
This one at Los Angeles international airport where an out-of-control car smashed into one of the terminals critically injuring a 9-year-old girl. ABC's Ryan Owens is at L.A.X. With the latest. Good morning, Ryan. Reporter: Hey, George, good morning to you. You see that plywood behind me. That's the place where the driver slammed into the terminal. He barely missed crowds of passengers but as you said, he did hit that little girl. Crashed into the window. He crashed into the wall. How is he going that fast? Reporter: Tragedy at the terminal. Three are injured including a 9-year-old girl after a driver plows through this wall at L.A.X. One of this country's busiest airports. Authorities believe the 67-year-old man behind the wheel of his Porsche was dropping off a passenger here at terminal 7 Sunday evening when he confused his gas pedal with his brake. The little girl was flying through the air. She clearly hit her head. She was unconscious, everybody was yelling for a doctor. Reporter: The 9-year-old who was on the curb with her mother and siblings when she was hit is still in critical condition this morning. The driver and his male passenger were both injured, as well. But not seriously. Investigators aren't sure how fast he accelerated but his luxury sports car ended up deep in a supply room, just above a stairwell. Where this tsa agent was storing his bikecycle. Looks like I'll be using the bus for awhile. Reporter: This morning police do not believe the driver was under the influence at all. Again, they just think this was a terrible accident. One that, robin, could have been a whole lot worse. All right, Ryan, thank you.
