Maybe power it the way the black box is powered, a stand alone system that transmits location and data that is typically also logged to the black boxes.
I'm sure satellite coverage is an issue with getting data in remote areas, maybe SpaceX's StarLink system could provide a way to stream data from airliners in more locations.
No I'm asking how do you put attribution to the physical flipping of a breaker especially against someone just cutting the whole electrical system out at the same time with a master breaker.
Satellite coverage isn't really an issue there's already stuff like Inmarsat's network that covers all but basically the poles. [0] Has SpaceX advertised or said anything about covering the poles? I doubt they will just because there are so few customers.
