Presuming that there's a post-mortem on this, it would be interesting to read if ever made public (quite doubtful). How many different processes had to either not exist or have failed for this to have happened? Surely, the military would require secured communications for such devices, wouldn't it? I presume that the manufacturer didn't outright lie to the military about the lack of encryption and that the military actively participated in the specification process. This, along with the drone video issue, is really quite strange.
