The summer of 2018 i was in the habit of leaving my house about 2 am for a walk. about 5 minutes into my walk i was looking at ursa major in the north west sector of the sky. there were low puffy clouds about 6 to 700 hundred feet off the ground covering about 50% of the sky. i was walking along wishing i had my camera because the clouds framed the whole constellation. not just the dipper. all of a sudden this bright white light appeared over my right shoulder going faster than anything i've ever seen. from almost directly overhead to over the horizon in 4 seconds or less. as it passed over or through the tops of the clouds it lit them up like the full moon. i tensed up bracing for the sound wave to hit me. it never came. it was going to the north passing near the 700 wlw radio tower, about twice the height of the tower. i thought if it was going to wright patterson (about 30 miles to the north) it would never slow down fast enough. it appeared to be doing at least mach 4. then i realized it did not make a sound. something moving that fast and less than a 1/4 mile overhead not making a sound made no sense to me. i do not remember the exact date but it was between the 4th of july and my birthday on the 19th 2018. 2:05 - 2:10 am. i am sure the way it lit up the clouds it could have been imaged by satellites. look for the night with low puffy clouds. april 2019 i had an idea that made me question general relativity. i have been trying to get the government to listen. they don't respond. anyway i believe i know how these things are possible. have not told them that. i just want them to look for something in the gps array and compare it to ligo. if someone would like to discuss the physics behind these things let me know.
