We were driving from San Francisco to Tucson in late May 2008. We always film our road trips with a camcorder. Taking it out and casually filming the highway, traffic, landscapes, sky…whatever. It was only upon reviewing this footage years later, that this black object hurtling across the sky was discovered. We have no idea what it is we filmed as it flew over so fast, we did not see it at the time. At first we thought it may have been a military jet or missile. It travels so fast but has no apparent wings.
