Driving Southbound on the A51 with my wife. She noticed four lights close together toward the south and commented "how close those planes are stacked up together. The four lights moved to the north. We saw that three of them in a triangle formation that were solid light lights, and a fourth light lower in altitude, trailing that was white with blinking red and blue lights like a helicopter or plane following the other three. Pulled off the freeway at Greenway road and found a parking lot to get a better look. By that time the lights were all far off to the north and appeared to be in more of a line.
