Silent, high altitude fast moving.

My toddler thought she spotted a bird and pointed to myself and her mother a football shaped object passing just below the high-thin cirrus cloud layer. I observed the object as I observed many in my 20 year military career at sea. This was not a drone or hobby grade RC… as I am an RC pilot I can confirm that with certainty. The sunset backlit the object so it appeared nearly black in color but a few times a “shine” or “gleam” of light could be seen. The travel speed and trajectory were very deliberate. The altitude was high and the object was going at least double the speed of a commercial airliner. No wings, no mechanical motion and no exhaust were present. No noise what so ever was heard. We watched from horizon to horizon as the object passed from roughly southwest to northeast (left to right) across our view.
