Not backing off anything. That’s why I provided a link to a source saying Leyvas said 5:15. But if you are willing to discuss distance travelled at high speed, explain the lack of relative motion of what you believe is a missile with its rocket motor(s) still ignited climbing into the sky. Keep in mind, it takes something like the space shuttle a little under 2 minutes to reach 150,000’ at which point it is moving at 3000 mph.
Well, you should back off. "About" doesn't say exactly when he started filming at all. At any rate we already eliminated UPS902 for certain by the criterion we just discussed a few posts ago. Add to that Gil Leyvas' own testimony that he saw the contrail of an airplane well south of what he filmed and we have two good reasons to leave UPS902 out of any discussion of this.
