What's all the Buzz about? It may be what gave them their name, but it's what we hate most about them: Drones are a pain in the ears. The race is on, before they are pressed into service, to cure this device's greatest headache

In fact, within industry, drones are already successfully used. They are abundant in the entertainment industry for filming, and within the oil & gas and utilities industries for remote monitoring. With consumers, their use has mainly been recreational, but that's all about to change.
