Was driving home at 9pm, in the country backroad of fm 718 (33.0642032, -97.5190962) it is very dark and there are some stars visible out here. i noticed an extremely large dark triangle shape in the sky almost directly above me. it did not appear to be moving but more so hovering. each corner of the triangle had a light with a blue hue to it, each light was twice the size of the northern star and was very bright. as soon as i turned on fm 4668 (33.0514848, -97.5321043) the object was out of view, a short time later i saw an airplane that was moving at a regular speed and had flashing red and yellow lights.
