Rising UFO come out from the boomerang

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 .
