We where at moffet field to work at the commisarry. Wanted a pic of the hanger because its been stripped and it looks a really cool. It was early morning so nothing was flying yet then the object appeared. I didn't notice it until I was gonna take the pic of the hanger. I looked everywhere for planes and seen none. First it was just hovering then darted about 4 times in all directions but just short burst then hovered again before disappearing while not looking tryn to get cell to zoom in clearly. I do believe in life elsewhere however never thought I would see such an obviously perfect proof.the pix are just from a cell phone and I have the originals on the phone still for proof of no trickery.
