'An Operational Puzzle:' Preventing Future Plane Crashes

James Cash has spent nearly three decades working to solve, and prevent, plane crashes.

James Cash has spent nearly three decades successfully deciphering information from electronic recording devices to help determine the causes of major aviation and other transportation accidents, leading to reforms and greater safety for the traveling public. Working at the National Transportation Safety Board (NTSB) , Cash is the government’s top expert on cockpit voice recorders—the black box devices that record the voices of pilots, co-pilots and engineers during flights, and are used to help determine the system failures and human errors that cause airplane crashes.

Over the years, Cash has played a pivotal role in the development and use of sophisticated audio, video and data recording devices used to help airlines and other transportation providers determine the causes of accidents, correct serious deficiencies and potentially save countless lives. His job has evolved from extracting information from tape recordings to the use of sophisticated electronic technology.

For his lifetime of work, Cash was a recipient of the 2012 Service to America Medal Career Achievement Award.

Watch how Cash spent his career helping put to rest the mysteries behind some of the nation's most notorious air travel incidents:
