If we were to create a list of "top places you shouldn't fly a drone," airports would certainly rank high. As the BBC reports, the UK's Civil Aviation Authority (CAA) has recorded six incidents between May 2014 and March 2015 where drones have almost collided with aircraft. In one instance, the wing of an Airbus A320 passed 6 meters below a quadcopter flying near Heathrow airport. To combat the problem and reckless drone flying in general, the CAA has created a "Drone Safety Awareness Day" and a "Dronecode" to better educate pilots. The latter is a streamlined version of its existing UAV rules: keep your drone within sight and less than 400 feet high, stay away from aircraft and airports, and use common sense to keep others safe. They're worth adhering to, otherwise you risk having your drone confiscated or, at the very least, receiving a good earful from the police.
