Cigar shaped craft seen northwest of Eugene at 9:30pm on May 14th

Sorry for not following the directions and using a word processor......                            While walking we observed a long cigar shaped craft to the northwest of Eugene. We watched it slowly move in a manner unlike any plane or balloon. It was grayish yet illuminated in such a way that seemed translucent We watched it for 10 minutes . We agreed that it was not a balloon and had no wings and it was silent .We tried to use our phones to record it but the lighting made it unviewable except for a blurry long light.I have always been a skeptic of UFOs but now im seeking more data to understand what it was we all saw. There was no propulsion system as it seemed to be using some other type of flight capability beside the conventional type...
