eli5 Why can’t black boxes in Aeroplanes update data to a cloud throughout a flight or after a crash has occured? why do we need to find the physical box?

In a lot of accident scenarios something unusual happens with severe weather or loss of control. Those things are also likely to disrupt a satellite link – it’s really hard to transmit through a thunderstorm and it’s hard to keep a microwave beam pointed at a satellite if you’re tumbling through the air.
In fact, navigation or flight-instrument problems make it hard to know where you are in relation to satellites, so in those scenarios you probably would lose the connection as well.
I think it could be worth trying but in many cases the data would be missing until you find the memory modules anyway.
