Fast-moving, pulsing orange light. Silent and erratic movements over northern TexasThis evening, My Wife and I were sitting outside in our backyard here in northern Texas, chatting and having a cup of coffee. When we both noticed an oddly-colored light moving quickly across the sky. We are no strangers to the airport traffic flying over head each night, this was different.What we saw was a seemingly high-flying object heading north towards Lubbock (some 30 miles north of us). What struck us as odd was that there was NO sound, which in itself is very unusual. Here in the southern Plains, We can hear aircraft from miles away.. The sound really travels.But it wasn’t just the silence that caught our attention, the navigational lights that we always see were “off” as well… as in not there. The only light we could see, was a very bright, burnt-orange color that seemed to be pulsing. Almost as if some sort of thrust or propulsion.We watched the object head due-north for almost a minute, then it pulled a HARD bank to the left forming a 90 degree turn and flew due-west towards Nevada until it disappeared over the horizon.I know an argument can be made that perhaps the angle did not allow me to see the nav lights. And that would be an understandable argument… if not for the fact that the object, having pulled a sharp 90 degree turn in the sky above my head, showed Me two sngels and still no lights. Together with the fact that I am ex-spec ops and very familiar with both aircraft, and what to look for. This is something I have never seen before.
