I think most drones for private use are going to fall in the Class G airspace below 1200 feet, and a lot of the hobbyist are going to be way lower like 100 feet..if its a plane at 10,000 feet I'm less concerned with the intrusiveness of pictures being taken. We have drones that fly at 90,000 that you'd never even know are there http://www.zdnet.com/article/faceboo...-a-boeing-737/ .....so clearly some guidelines will need to be set on height limits for trespassing
