Black box flight recorders didn't save my life directly, but I'm sure that with the number of flights I've taken in my life, my chances of dying are much lower now thanks to improved airline safety. Those improvements are a result of the investigations helped by the black box flight recorder. So it's saved my life as much as an airbag: not directly from personal experience, but by saving the source of information about a crash and improving overall safety as a result.
