I was driving south down strawberry rd in pasadena, texas when i saw three lights creating a triangle form in the distance. i parked and watched since they seemed to just hover in place, blinking. it was pretty dark since this is a back road and the lights didn’t move as a normal aircraft would.
they moved slowly, but always maintained the triangle form and position. after maybe 30 minutes, a fourth appeared and a diamond form was created. the lights seemed to flicker randomly. this lasted for 3 hours. then they suddenly went off in separate directions. i observed this happening again for a few more years around the same time of year.
