Black Triangle Sighting in Morden, Manitoba on 2018-07-30 23:50:00 – Silent transparent triangle

My son and myself were out tracking satellites with a phone app to see if we could see them as the past over. suddenly i saw something approaching from the west that looked odd. i asked my son of he was seeing the same thing. he's 7 and started to describe what he was seeing. in his words it looked like a single wing you could see through. we both agreed that the shape was indeed a triangle. he also stated that there were circles in the object. the stars were distorted through the object as it flew completely silent with no lighrs of any kind. the entire ex was less than a minute long.
