Possible.
You can't overlook the fact that what he experienced occurred- after the night sightings. He could of had ET's on the brain.
The cone shaped grid in a very low contrast image could have been floaters. So could seeing the objects as a blip from the left and the right.
I just want to know what the background sky looked like. Was it clear? Was it lightly cloudy or was it overcast- grey. Had the sun set and why was it so hard for this guy to see an "edge"? (Don't say "because it was big":))
