For about the sixth time, in only about two weeks, I am prompted to remind people of this:
Just recently -- only a couple of months ago -- a Federal judge ruled that the FAA has no authority over small low-altitude drones or models, regardless of whether they are being used commercially.
The ruling has been stayed pending appeal, but the judge ruled on the basis that it was never Congress' intent to give FAA authority to do this, and his argument was very strong.
In the meantime, the FAA has seemed to be intent on regulating everything in sight, before the appeals court slaps them down... which it is extremely likely that it will do, since it is pretty clear that it wasn't, in fact, Congress' intent to give the FAA such authority.
In that way, they have been acting just like the EPA, apparently trying to usurp every possible authority they can before the 2014 elections. I have no other explanation for their sudden, intense attempts to pass further regulations.
