2 nights in a row, both nights at appx 6:45pm cst, moving much faster than any jet I've seen, going appx from sw to ne, saw a glowing, slowly pulsating white light. No other lights normally seen on a jet or plane. Pulsated every 4 to 5 seconds, going from bright to dim to bright again. Not on and off. No sound Straight path until out of sight. Slightly different flight path 2nd night from 1st. My 28yr old son witnessed the 2nd sighting and verified these details. I am regular star gazer, have seen some anomolies, but nothing like this.
