Huge TriangleWhile stargazing with my 8 inch Dobsonian telescope, me, my wife, and a friend noticed what appeared at first to be 2 aircraft flying in formation with one trailing the other. The objects had a triangular white light pattern with a red strobe between the two objects closer to the front. The first object was smaller in size than the second object. I managed to track the formation with my telescope for a couple of seconds and it appeared to be one object shaped like an isosceles triangle. If it were 2 aircraft then I would have noticed irregularities in the distance between the two, but there was no lateral movement between the two, they kept a very static distance between them. I believe the shape was distorted because it appeared to be between 2 to 5 miles to my South.The red strobe seemed to be huge and I could faintly see the outline of the back end in the telescope. The object moved across the entire sky in less than one minute without making a sound. When I held my fingers up at arm’s length the object seemed to take up 3 fingers worth of sky. If I were to estimate the height I would guess that it was probably between 5,000 and 10,000 feet up. I have never seen an aircraft of this size in the sky.We live near Tinker AFB and have seen just about every aircraft in the inventory. This thing was way bigger than a C-5 galaxy and moved much faster without making a sound.The object was moving in an ESE direction.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
