SEOUL, South Korea (AP) — The black boxes of a Boeing jetliner that crashed in South Korea last month stopped recording about four minutes before the accident, South Korean officials said Saturday, possibly complicating investigations into the cause of the disaster that killed 179 people.
I don’t know, I doubt these recorders are made by the aircraft companies.
Aren’t they mostly self-contained units, and just connected to aircraft power to maintain their batteries?
I’m a lot more suspicious.
Their power supply comes from the plane so they stopped recording because power delivery was not designed faile safe. Now guess who designed the power supply?
