Looked up into sky at the moon, saw a whitish-silver, rounded double decker bus shaped object flying in a northern direction

This morning at 7:55 AM I was walking my dog and looked up into the sky and saw the moon. I was standing on Spring Street at the corner of Fourth Street at that time. To the lower right of the moon there was an odd shaped flying object in the sky that was clearly visible and not a plane. It was whitish-silver in color, it had the appearance of a solid object that resembled a rounded edged double decker bus. At one point it briefly changed shape into a flatter version within a gray cloud of dust then returned to the rounded double decker bus shape and the gray cloud of dust disappeared as quickly as it appeared. The object flew in a northern direction for approximately 5 minutes as I walked along the street with my dog and then it disappeared from view when the bright sunlight struck the object as I reached the corner of Spring and E. Morehead Streets. When it was visible it was extremely high in the sky and there was no exhaust trail.
