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?

Totally agree, you can make a new black box or call it any way without removing the old, adding redundancy and more possibilities to find at least one of them. Not like jets are sold cheap and they need to cut corners on safety.
I always thought it would be nice to have those inflatable balloons on the plane like they use on rovers dropped on Mars.
If the plane goes down it just opens up a parachute and inflates a ball around itself and falls to earth no problem.

Crashes are pretty rare. You would need to stream all the black box data of all planes all the time in order to catch the few instances where you actually have a crash.
That’s a lot of constant network traffic to deal with for not a lot of instances where you need it.
On top of that you would *still* have to consider the scenario that there’s a technical problem with transmission immediately before the accident, in which case you’ll want the black box as a backup anyway.
It’s also important to note that searching for the black box isn’t a huge effort on top of the normal crash response and investigation. A lot of responders or search vehicles are going into that area anyway to search for survivors, dead people, wreckage, clues… and the black box. Even if you had all the data streamed to you, you’d still be doing most of that.

There’s no guarantee that you’ll have a channel to transmit all that information, and even if you did, that it would arrive intact. Hence you store it locally for later retrieval.

Quite simply because, until the recent advent of SpaceX Starlink, no satellite data service existed that would affordably provide the bitrate necessary.
