We really don't. Satellite uplinks don't have enough bandwith for every plane's black box data, and the data we would get wouldn't be useful, since you need the data when things go wrong, and I doubt you'll maintain a connection when everything goes wrong. Furthermore this article illustrates why I try not to read the news at all. The journalist has absolutely no idea what he's talking about - which is the norm for most stories. Film streaming is done from an on plane cache and in air WiFi is more often than not provided by ground cellular networks, falling back to satellite, which is unusable most of the time.
