Bugs and unknowns version 2

The dark objects in this picture are bugs close up and seen during the shot. The other two however are something else altogether. The bugs are moving south to north while the two "orbs" are moving north to south. To the eye these white objects appear to be solid, about the size of a mini van and highly reflective. They make no sound and blend in with the blue sky quite well. They appear to be the same type that was seen in my photos of the sundog. Will have to put in some overtime to buy better equipment to help solve this puzzle.
