An anonymous reader writes: Back in February, officials at the Federal Aviation Administration told a Texas search-and-rescue team that they couldn't use drones help locate missions persons. The team, which is called EquuSearch, challenged the FAA in court. On Friday, the court ruled (PDF) in favor of EquuSearch, saying the FAA's directive was "not a formal cease-and-desist letter representing the agency’s final conclusion." EquuSearch intends to resume using the drones immediately. This puts the FAA in the position of having to either initiate formal proceedings against EquuSearch, which is clearly operating to the benefit of society (as opposed to commercial drone use), or to revisit and finalize its rules for small aircraft entirely. The latter would be a lengthy process because "Congress has delegated rule making powers to its agencies, but the Administrative Procedures Act requires the agencies to provide a public notice and comment period first."
