Rods gain their name from their rodlike shape. However, they have also been called "flying rods", "skyfish" and "solar entities". They appear to be anywhere from 12 cm to 50 meters in length.[citation needed] Rods can control their flight path as birds and insects do.[citation needed] Rods are not classified as atmospheric beasts because rods are nearly always described as much smaller than atmospheric beasts and as invisible to the naked eye; in addition, rods have a much shorter history as a subject of research in cryptozoology and the paranormal.
They almost look like flying missles (notice the 4 wings) like UAV's..
