I ruled out clouds as there are none low flying nor any fast moving, so I'm not sure what it was...Ten minutes ago I saw three huge shadows cast across my yard and moving fast...I saw this on my security cameras, plural is correct because it went across three cameras...I immediately went outside and looked but saw no cloud movements and nothing else flying around which could cast these shadows...The shadow footprints were huge, covering at least half an acre per shadow, one right after the other...I heard no plane engines nor helicopter engines, no drones and no birds around here could cast such a shadow...I really thought it was cloud movements but there are no fast moving clouds around, just very high upper atmosphere clouds...Strange...
