Robust contrail with no obvious traditional aircraft.

I was watching the sun come on a cloudless morning. There were a few jets and some Contrails but nothing out of the ordinary until this object came streaking across the sky. The speed and robust contrail is what caught my eye at first. It was hard getting it in frame at full focus but when I did I noticed the contrail was missing something. A traditional aircraft. I did my best to get something useable but these two were it and it was gone. Horizon to horizon. To guess the exact time it took to cross would be just that. A guess.
There was no sound but whatever it was it was way up there.
