3 white lights in the shape of a triangle, observed for 5minutesI was about a mile south on TX hwy 70 from the FM 283 turnoff. I was at work on an oil well. What I saw was 3 white lights in the shape of a triangle with a red flashing light in the center. It was traveling in an easterly direction. From my prospective, it seemed to be moving slower than an airplane. I've been working on night shift for almost 6 years and this is the 1st time that I have ever seen anything like that.
