Remember those drones the Nationals were flying at spring training practice down in Viera? The ones that were taking pictures for scoreboard promotions later in the season? It appears there may have been a specific reason for the discontinuing of their use.
The Federal Aviation Administration, in fact, had a problem with the Nationals' employment of drones, stating they were against FAA regulations.
Read this from CBS News:
"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," a team official said when contacted by The Associated Press. The drone flights ceased the next day. The official wasn't authorized to speak publicly and asked not to be named.
The Nationals, evidently, were not supposed to be flying them, even if they were for such a benign reason. According to CBS, it's quite difficult to obtain permission from the government to use drones, no matter the purpose.
The Nats were rather innovative with the idea of using drones, but perhaps the method was a bit ahead of its time.
