A giant 'string' of about 50 lights moving high and fast in a perfect line. star like but very bright. the line seemed to have a pattern of 3 space 4 space 3 space 4 and so on. it moved from the horizon in the west toward the southeast sky above and then seemed to fade out or disappear into the clear sky in order , not all at once. almost like a train going into a tunnel. we could still see stars at the spot where the lights disappeared. if i had to guess i would say it was a mile long but very high up. the lights did not blink at all, but were like very bright stars. almost twinkled. we pulled over and tried to get a picture but my phone camera wouldn't pick it up. the whole thing lasted about 2-3 minutes.
