The National Transportation Safety Board ruled on Tuesday that drones are regular aircraft and are to be treated as such. This ruling basically affirms the Federal Aviation Administration’s authority over the drone industry which is growing by leaps and bounds. The problem is the agency has not come out with a clear cut set of guidelines yet for commercial use. Not good news for Amazon.com which earlier this year asked the FAA for permission to test the miniature flight vehicles in open U.S. airspace. It wanted to test package delivery using drones. The idea was to drop off items weighing less than 5 pounds within a 10-mile radius of Amazon’s warehouses. Still businesses are getting impatient as they wait for the FAA to regulate the use of drones in U.S. skies. Right now, recreational use is allowed but there is an almost ban of their use for commercial purposes.
