Forget drones: These tethered blimps can spy on cities belowhttp://arstechnica.com/tech-policy/2014 ... ies-below/Patrolling the skies these days is hard. There are so many options to choose from: traditional helicopters, new wide-angle surveillance planes, and even the more cutting-edge drones.
Each of these options has its drawbacks. Beyond the initial purchase price, well-tested helicopters typically cost at least hundreds of dollars per hour to send up. One-off surveillance planes are also not cheap, coming in at around $1,000 per hour. Drones, while very cheap, are problematic. Law enforcement needs a blanket Certificates of Authorization (COA) from the Federal Aviation Administration (FAA) and possibly a specific Notice to Airmen (NOTAM) each time a drone is used above 400 feet.
