On Monday, citing a congressional mandate and reports of drones near airplanes, the FAA announced that any unmanned flying vehicle heavier than half a pound would have to be registered with the government by February 19th, 2016. This is a huge change for the hobby, and one the FAA says it's implementing out of an overriding concern with safety. There's just one catch: if the FAA really wanted to protect planes from small, autonomous, unmanned objects — they'd ban turtles first.

At least, that's the argument of Eli Dourado, an economist and technologist at the libertarian Mercatus Center. Using data pulled from the FAA's own database of wildlife strikes, he created the chart above and posted it on Twitter earlier today. Since 1990, the FAA recorded 198 airplane-and-turtle collisions, and exactly zero drone-and-airplane collisions. Even when the FAA warned about an increase in drone and airplane "encounters" earlier this year, the encounters were limited to drone sightings, not actual collisions.
