Well your picture helps a lot. I assume the pointy end was in the direction of travel and the two arms were trailing?
Yes. Whaddaya think? I know it looks a lot like the pics you've posted of regular ol' jets (if there's any such thing!). Again, husband insists that at such a high altitude as this was, condensation couldn't have existed, and it was way, way too far off to see the glow of afterburners. Is there such thing as an Aurora, and if so, perhaps is this what this was? Also, check Freepmail.
