On a side note : What if the emitter of the black boxes simply didn't work ?
Before being accused of too big "whatification", a little digression : 3 helicopters of the same type & operator were lost (crash) in the past years. Said 3 helicopters were equipped with a 406MHz emergency beacon. No beacon ever emitted, as they were separated from their battery in each of the 3 crashes.
I suppose some redesign is to be done to those emergency beacons, but so far...
