They speed up as they re-enter and it is all over in a single orbit or so. Lots of hams captured the re-entry of the APRS RAFT satellite and you can see it warming over the last few days and then rapid rise in the last 12 hours or so:

It was still working up to 2 hours before re-entry. Might have even been closer, but we may not have had someone in range of it on its last bleep...

I am wondering if, as a Sat. decays, getting closer to Earth, will there be "better" comms ? Guess they will be moving faster. Will the Keps "decay"? Interference from "reentry" heating ? Battery's gone first ? Solar panels "ripped" off. Or, Just GONE ! Orbital mechanics at it best. Wondering what the "mechanics" of re-entry are. Can't be "pretty". Poor little satellites. So many people, worked SO hard to get them there. Just curious.
