Watched the object move north-west at approximately 5:15pm, which would have traveled directly over dfw airport, and was constantly gaining altitude. was in the pool at the time, so didn't have a phone to capture images or video. at first i thought it was a cylinder object. then it appeared to change shape and look like two spheres connected by a line. it reflected in the sun. i also thought it could have been balloons interconnected, but realized it was moving too fast, it was too large, and moved in too much of a straight line. the two spheres constantly moved around each other, appearing to be connected the whole time. observed for approximately 5 mins until it went to high to see/lost in the clouds.
