Drones normally do not fall out the sky all of a sudden (unless maybe it’s a Karma), but every so often it does happen. As it did to Efrem. On a school trip to Iceland, he brought his drone along to capture some of Iceland’s amazing scenery. Skogafoss Waterfall was the third waterfall he was flying his drone. Then his Phantom 4 suddenly lost the connection to the controller and dropped out of the sky.
