Absolutely enormous glowing white boomerang shaped object flying north to south. i first thought it was a cloud, as i saw it out of my periphery, but realized it was moving extremely fast. it had to be very high, as there were no distinguishing characteristics. this object was truly enormous and completely silent. the color was completely even, it really looked like a lit cloud. multiple planes were in the sky, as dfw and love field airports are close by. this occurred about 9:50 pm (cst). i was out with my dogs. biggest object i’ve ever seen flying in the sky.
