The craft moved about in the sky just like a hummingbird or a bee. It looked to be the size of a VW Bug.

Early morning on a spring day sitting on front porch(tying laces waiting on bus) a very shiny round metallic object that looked to be the size of a VW bug appeared out of the southwest sky moving fast and then quickly stop and hovered over an open field. 
The craft then moved much like a hummingbird or bee.  The color of the craft looked to me like the burnished side of alumium foil (shiny yet somewhat dulled.)
The craft manuevered for one or two minutes and rolled out and upward. This movement looked like a jet whose pilot pulled back and to the right causing the craft to turn on its edge while accelarating away to the northeast. The craft looked to be 300 to 400 yards up in the sky. 
As it left it crossed the route of the school bus. Several of the riders claimed to have seen it as well. The bus driver denied seeing the UFO.
Witness indicates that date of incident is approximate.  PD
