None of the stories I've seen on this do a good job of emphasizing that point that this is but a first step towards the possibility of in-flight use - we're talking a matter of years, not tomorrow. There's a whole host of technical, political and procedural issues to get through first. (CNN is better than what was in the Wash Post this morning)
What prompted this was an
announcement that the FCC will consider a Notice of Proposed Rulemaking at the December open meeting next week. A NPRM isn't binding and is but the first step to develop a record on which to change or implement rules. The NPRM isn't even adopted or released at this point, so anything as to what will or can be done is speculation.
