This rising ufo’s original shape is dome like. when it flies too fast, the shape becomes prolonged or even triangle looking. if it changes the direction the body shape has a little curve ( that is what we call it shape shifted). it is not alien's nut and bolt type or our military's . This dome ufo come out from the boomerang and the boomerang UFO is form by 10 dome shape UFOs: http://ufo-spacelife.blogspot.co.nz/2011/05/boomerang-formed-by-dome-shaped-ufos.html . I got many photos about UFO rising from my back yard: https://ufo-spacelife.blogspot.com/2013/09/ufo-rising-from-my-back-yard.html
