On May 8,  2004 I was driving a BMW with my sister as a passenger. I was driving along the I-5 freeway at around noon when suddenly, emerging from the clouds, approximately 1 mile away and 1/2 a mile up a silvery object, due to its brilliance,  caught my attention against a backdrop of white stratocumulus, slightly to the right of my car. The object was easily visible from a near perfect sky.

 Thinking that the object was perhaps a cargo plane, I banked to the left lane and immediately ask my sister if there was any air traffic in the vicinity other than the object. The reply was negative. As I completed the lane change, the unknown object suddenly appeared at my 1 o’clock position (no more than a mile away) to change shape. And it was definitely not a cargo plane. The upper section, not concealed by any cloud, was gray, and on the lower section there appeared to be one or two reflective bright silver panels. The object was approximately  13 to 15 meters in diameter. Suddenly it accelerated and vanished from what I believe was a slow moving position.

We sped up to get a good look but the object was gone.
