Recently, there was a significant "news buzz" when Chris Roberts, a computer security researcher, was removed from an airplane after tweeting comments about the ability to access "critical" aircraft data via an underseat passenger connection available at each seat. These connections were intended to allow passengers to access the Internet and other harmless flight information. But Roberts, being a security expert, says that he has been able to access functions, like deploying the oxygen masks that might panic passengers and endanger a flight.
