oh this suddenly got way more interesting. how in the world is it possible to cause a FDR to stop recording, and how did that happen to both of them at the same time? isn't this precisely why they have two? fascinating

@infosecdj I didn’t know you read French :?
The plane was apparently old enough that the black boxes didn’t need to be on separate/redundant power supplies. The power cut out exactly at the same time as the bird strike occurred, so it seems the main power for the plane was derived off the impacted engine (engines?).

@teotwaki so both CVR and FDR, both of each, are tied to the same power source? and that source powers everything in the plane and is located in whichever engine it is? wow, that's a sound engineering decision for sure...
that said, how did they even stay in air for 4 whole minutes if all power was lost? so many questions here
I wonder if this will change EASA's mind now.
