There is no added safety with new recorders or continuous transmission , the only difference being that it may be found by now and a story about what happened, although nice to know still resulted in the deaths of 239 people.
Disagree. With new tech we can help prevent the next airplane go missing and save its occupants. If we just shrug, we'll eventually get more of the same type of accident as this.
All aircraft boxes need CIrcuit breakers to protect wiring and prevent fires , they can all be turned off and that cannot change.
However, by making a circuit breaker smart it can report if it was manually tripped ( = tampered with, unless there was a good reason) or by overcurrent.
