But we need to do something besides crop dusting. Look at the deadzone in the Gulf of Mexico if you have any doubt.
Because of high concentrations of pesticides - If you could spray more frequently, you would not need the high concentrations, therefore less run off... A UAV could be as cheap to operate as any other farm implement without needing specialized training to operate.
Postal/parcel delivery of perhaps the most important things, like organ transplants or something. Otherwise the use is over the top.
Have you ever tried to get next-day delivery to a rural area? There are many parts of the country still that are over 200-300 miles from any major airport. Private pilots are often contracted by the USPS to ferry mail back and forth to these areas.
Search and rescue, maybe. Would Steve Fossett have been found any sooner?
Quite possibly - Pilots are limited to how long they can fly per day. Because there is a shortage of qualified pilots, it limits the time and increases the expense of search and rescue operations.
