Unlike many other vehicles operating with heightened safety concerns, airline cockpits don't come with video surveillance. The reason, in part, is that airline pilots and their unions have argued vigorously against what they see as an invasion of privacy that would not improve aviation safety. The long debate on whether airplane cockpits in the U.S. should be equipped with cameras dates back at least 15 years, when the National Transportation Safety Board (NTSB) first pushed regulators to require video monitoring following what the agency called "several accidents involving a lack of information regarding crewmember actions and the flight deck environment." The latest NTSB recommendation for a cockpit image system (PDF) came in January 2015. Should video streams captured inside the plane become a standard part of aviation safety measures?
