Drone operations over Somalia pose danger to air traffic -UN — RT

It is pretty obvious that drones are gong to be used over cities and towns in non war zones. The story will go that they are cheaper than helicopters and can fly longer,which is actually true. A helicopter is big enough to appear on radar whereas a drone is not. So what happens, over an urban area, near to a major flight channel? Aircraft tend to fly within corridors at between 30 to 40,000 feet on long haul flights, right where the drones operate. How soon will it be that a drone and a jumbo are in collision?
