The FAA lost the first round in court already. Additionally it has refused to openly engage in rule making on UAVs in the national airspace. What is going on is being slow rolled.
They cannot continue to put their head in the sand or they will simply be bypassed as they are today.
The FAA lost because of the wording of the rules. AT that time I figured the FAA would retreat and come out with their guns blazing and put an end to it once and for all.
Their new rules are to come out in early 2015 so we will see.
