Why Investors Need to Be on the Lookout for Aerial Drones

"The higher you climb, the more that you see."
-- Folk singer Dan Fogelberg

For decades, that's been true, and some of the best "seeing" that humans have done in years past has been done with the help of satellites. These multi-ton hunks of metal orbit the globe, taking snapshots and shooting video with their high-tech cameras, creating the images we see today on Mapquest, Google Earth, and Apple Maps.

Satellites have proven themselves invaluable in producing detailed, high-altitude photography. The problem is, they cost a lot -- both to build and to launch into space. (Even space start-up SpaceX charges $62 million to put a satellite in orbit.)
