Try this: In the "properties" for the camera set it to "point at" your objects center, then "group" your camera (with nothing but you need to do this for next step). Now position the "hot point" for the new camera group to same position as the center of your object that you are "flying" around, leave the camera where it is. Now, in the camera group properties window add the "Spin" Behavior. Then drag your time-line marker & watch it fly!
