Influx Of Cylinder-Shaped UFOs - Why?

In this phase of UFO presence in Earth skies, why is there an influx of usually large cylinder-shaped objects? They are being reported all over the globe which makes one doubt that they are some form of U.S. military, NATO, Russian, or Chinese drones. Besides, have humans of any nationality really managed to create drones with no discernible ability to fly? There are no wings for lift and how in the heck do you get a cumbersome-looking tube to fly? Somehow it is easier to accept that graceful science fiction-looking saucers can fly with no wings but these cylinders?

This case is reported by an aerospace engineering major who has spent a lot of time researching “flying” in all forms. Be sure to read the comments below the report of this case. One comment mentions many cylinder sightings in the 1400-1500s in Germany in particular, with the theory that there was a war amongst alien cylinders and orbs.

I googled this information and found this at www.ufoevidence.org:

At sunrise on the 14th April 1561, the citizens of Nuremberg beheld “A very frightful spectacle.” The sky appeared to fill with cylindrical objects from which red, black, orange and blue white disks and globes emerged. Crosses and tubes resembling cannon barrels also appeared whereupon the objects promptly “began to fight one another.” This event is depicted in a famous 16th century woodcut by Hans Glaser.

Back to the present, there are also reports of many orb sightings worldwide so we can only hope there won’t be another galactic war in our skies.

“Tube” indicates that these objects are hollow or at least have space inside for corporeal beings whereas a “cylinder” could be fairly solid, perhaps the outer casing houses one big machine inside?

We should mention here that recently it was theorized that these sightings can be explained because the wings on certain types of airplanes at certain angles, do not show up. It depends on the light and angle. http://www.ufodigest.com/article/cigar-shaped-ufos-over-kansas-city-explained A few days ago, I watched what I suspected was a cylinder flying overhead but after keeping my focus on the object, I was finally able to discern the wings. There was no noise as there usually is with jets but probably the weather conditions were wrong for “noise.”

Depiction of what cylinders might be like “upclose”

However, as with the entire UFO phenomenon, the explanation that all cylinders are misidentified planes really doesn’t make sense. So, we wonder—are these cylinders actually like jumbo-jets without wings, thus they are a type of mothership? Perhaps they belong to one kind of UFO occupant while the huge orb, saucer, or triangle craft are the motherships of UFO occupants from other places or sources? Or at least these might be “interim ships” which are not as small as scout craft but not as large as the mother of all motherships.MORE HERE
