Black Triangle Sighting in Salem, Oregon on 2017-09-28 11:00:00 – Triangle shaped object that disappeared

The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:

I was walking my dog on the 700 block of sand piper st in salem oregon when i heard a propeller engine noise. i looked up but didn’t see an airplane. my attention was then drawn to an object that was passing overhead. it was white in color and appeared to be a solid object. i was traveling slightly faster than an airliner. as i watched i realized the object was triangular shaped. i watched it for maybe 15 seconds when it suddenly just disappeared. at first i thought it had passed into a cloud but it didn’t disappear like it had. it just vanished. i looked further along its path to see if it reappeared but it didn’t.
