BLITZER: Welcome back to our viewers in the United States and around the world. I'm Wolf Blitzer reporting from Washington. Boeing Airlines disputing sensational allegations that a passenger gained access to the plane's controls during a flight. According to federal court documents, Chris Roberts, a cybersecurity consultant based in Denver, claims he was able to hack into in-flight entertainment systems on up to 20 flights and from there get to other critical plane functions. But Boeing says it's not possible because the flight controls are isolated from the entertainment electronics. Still, the FBI says it's investigating after Roberts sent out disturbing tweets at a recent flight. Journalist Kim Zetter interviewed Roberts, wrote an important, in-depth article for "Wired" magazine. She's joining us. She's also the author of "Countdown to Zero Day." Also joining us, CNN safety analyst, former FAA safety inspector David Soucie. So, what exactly has Roberts claimed to be - claimed to have done, Kim?</s>KIM ZETTER, SENIOR REPORTER, WIRED.COM: Well, according to the FBI affidavit, he told the FBI back in February that he connected his laptop to a network box below the passenger seat and used a default password to get onto the entertainment fight - the in-flight entertainment system.
