I don't think it was. It was the wrong shape, not to mention that there were other identical contrails in the same area, which would suggest that several other ships of similar size had passed that way moments before the one that I saw. Besides, the Narada was too high up to leave a contrail like the ship that's seen on the horizon. The Narada was like suborbital and at the edge of the atmosphere or something.
