“The part needed to fix a CL-415 water bomber damaged in a drone strike in Los Angeles on Thursday was on its way to L.A. on Friday.” from AV Web today says it all. If you want unpiloted commercial operations in the National Airspace, be prepared to pay for the safety of others. Factor it into your business plan. The only regulation I need to see is one that requires an inaccessible/non-removeable kill switch on all drones that activates automatically if within a quarter mile of any aircraft with humans onboard.
