on july 27, 2017, around 8:15 pm my wife karla and i decided to go for a walk, about 10 minutes into our walk, i noticed a super bright light about a half mile away and thought it was a drone, so we started walking towards it. i remember thinking to myself that the light was much too big and bright to be a drone . at that time it must've been about 200 feet above ground, as it approached us it lowered to about 100 feet above ground and moving about 25 miles an hour or less. making no sound as it approached us i observed the shape of a boomerang front with a tail of a arrowhead, it was a flat black color, it had different colored lights flashing erraticly along the bottom perimeter of the craft. i briefly saw a cockpit which seemed to have a pilot moving around with a large head or helmet. i also noticed that there was huge tubing on the bottom of the craft in different directions. as a pilot myself, i was expecting a huge downwash of some sort, but nothing, the craft was extremely steady. as it passed over us, i could start to hear what sounded like a gigantic jet engine with a heavy growl, until it passed and went quiet again into the darkness. we were shocked what we had just seen, we couldn't take our eyes of this massive object, until it was gone. i regret telling my wife before we left our house that we didn't need our phones because we were together, i think of what we saw often
