Black Triangle Sighting in Herrin, Illinois on 2017-05-31 00:00:00 - Large triangle shape flying extremely fast no lights very low no sound or trail
While outside me and a friend was testing out my new telescope trying to focus in on saturn. we was out there for around an hour or so trying to figure it out. i was almost dialed in on saturn with the site scope when my friend quietly but urgently told me to look and nudged me. when i looked at what he was pointing at in the sky at first thinking a shooting star. but this was no shooting star. we saw a triangle shaped ship flying very fast and low. it was really like a glide with no noise no lights. it was only about 5 seconds but long enough for us both to tell it was something neither one of us was not supposed to see. it was almost like in a camoflauge/silhouette in the night sky. i'd say it was about 400ft wide and 300ft long. i can't say it is or is not related but i have had some weird physical and physiological events following this encounter.
