On april 13,2019 in mid-afternoon i witnessed a ufo flying over my house. it was traveling south to north, was very fast, and didn't make a sound. it was about as high as a jet airliner is when it is on approach to land(500ft?). i am sure it was a ufo because i saw the same type of craft 2-3 days before the incident. at that time the craft was a farther distance from me, flying from south to north and more east of me towards wyandotte and the detroit river.
