Last week, Major League Baseball fined the Boston Red Sox for not putting enough of its regular roster on the field for a spring training game. The Washington Nationals now face a fine of a different sort, for using a different sort of player during spring training—the team may face a penalty from the Federal Aviation Administration for using an unmanned aircraft to take promotional photos during a team practice.

When contacted by an Associated Press reporter regarding whether the team got FAA approval for use of the small drone, a team spokesperson said, “No, we didn’t get it cleared, but we don’t get our pop flies cleared either, and those go higher than this thing did.” But the team stopped flying the drone the next day—and team officials wouldn’t comment further.

Ars attempted to reach Kyle Brostowitz, the Nationals’ coordinator for baseball communications, but he did not reply to our requests for comment. A spokesperson for the FAA did not respond to inquiries regarding the Nationals or whether the FAA had contacted the team. But the FAA will soon be facing many more of these cases in the wake of a recent administrative court decision, in part thanks to the agency’s failure to issue a new set of rules on commercial drone use.

The FAA is in the midst of an appeal of the ruling by National Transportation Safety Board administrative judge Patrick Geraghty. In his findings in the FAA’s case against Team BlackSheep’s Raphael Pirker, Geraghty ruled that the FAA had no enforceable rules or regulations that could be used to classify small remote-controlled aircraft as unmanned aerial systems. The FAA’s interpretation of the rules, he said, could be applied to “a paper aircraft or toy balsa wood glider.”

That ruling has led a number of drone operators to open their doors for business. The husband-and-wife team of Terry and Belinda Kilby, who have produced aerial photography through a personal project called Elevated Element, have already formed a commercial drone services firm and have started bidding for commercial business as a result of the NTSB decision. CNN and other media companies are among the companies that have contacted them.

“We’d been following that case for a while,” Terry Kilby told Ars. “Once that ruling went through, we made the decision to pull the trigger. It still remains to be seen whether the ruling will hold, but we’re willing to take a risk... As things stand, we’re convinced there is no regulation. To be honest, we’re a little confused about why the FAA is still pursuing cases like these and not just working on getting a regulation out.”

After the Kilbys were featured in a Baltimore Sun article about the NTSB ruling, they were contacted within hours by their first potential customer. The advertising agency for MASN, the regional sports network owned by the Baltimore Orioles and the Washington Nationals, approached them for bids on aerial photography of Camden Yards.
