Realistically, that means a consumer grade drone. (So no grand ideas for re-purposing one of those drones that can fly from an island in the Indian Ocean, loiter for a few hours and then, under the guidance of some teenager in Florida, send a missile into some wedding party in the tribal areas of Pakistan.)
What is the range of a ~$5K drone? Payload? Battery life? Knowing these approximate parameters would be quite useful for putting one's thinking cap on. If anyone has a good idea, with payload and without payload, that could be helpful.
