Final words from jet came after systems shutdown

[Plucketeer]

23. I'm not familiar with the 777

or any other modern airliners. However, having spent many years as an aircraft electrician, I'm willing to bet there are banks of circuit breakers just a reach away from the flight crew. These circuit breakers serve the same purpose as those in your house - to protect an aircraft's wiring from possible overload and fire. Each power-using device is on a separate breaker so that if a shorted system draws too much current, it'll pop (disconnect). IF one of these breakers pops, the crew has the option to reset it or leave it alone. BUT.... those breakers can and MUST BE accessible to the flight crew to manually disable as they might deem fit if an emergency arose. So making those systems manually disable-able is not just a dumb oversight by the engineers.
