“Cloud” storage on top of black boxes...

These stories of black boxes that can or can't be located, then can or can't be deciphered should now be relics of the ancient aeronautical history. Planes can communicate with satellites, upload and store their info (cockpit and cabin voices or noises and engineering data) in real time on the cloud via satellite relay.

I could understand that, in order to be redundant we'd keep these “boxes”, but all flight data should be transmitted electronically on an ongoing basis to a safe and secure location away from the aircraft. Seems like a no-brainer to me.

If such a system had existed, it's quite plausible that the cockpit door could have been unlocked from a ground safety crew, just like satellites can unlock car doors when you lock yourself out...
