These two news anchors initially said (when it aired live) there was no plane in the area because they literally didn't see the orb. These two loonies acknowledged the orb after it was pointed out to them and called it a plane and confirmed it circled the buildings.
It cast its own shadow between the towers very clearly from chopper 4.
Look just below and left of the north tower hole.
