There is a likelihood that this photo is a hoax. According to the AOL article, "someone using the name Raji posted images on the Web site Craigslist, answered a few questions from UFO hunters around the world, and then just disappeared into cyberspace."
I have found alternative sources for the photos on flickr.com. In fact, there are a ton of photos uploaded as of March 28, 2008 on the TCorp account. TCorp has sixteen photos of the California Drone, including what appears to be two versions of the craft. The interesting thing about flickr.com is that it gives you the information about the camera used to take the photo. The original version of the photo above was taken with Konica Minolta DiMAGE X. Those who are searching for this "Raji" should keep this in mind. Several other flickr.com accounts also have photos, including hoax debunkers that have some interesting perspectives.
My impression of the California Drone photos is that they are hoaxes. Problems with the photo above? Although the angle of the sun/shades is similar across view of the photo, the angle is different in its depth. The light source between the object and the power lines is from the right side of the photo, but the light sources' height from the presumed ground is different. Also, the light intensity between direct sunlight on the object and the power line pole is much different. Another problem is focus. Both objects are in focus, but differently. It is almost as though they where taken with two different cameras.
