I observed, what i believed to be, two f-22 raptors in my area (sighted in a s-se direction) a few hours prior to ufo sighting (approx. 8-9am on dec. 1 2017). i assumed they were running dogfighting exercises since they appeared to be moving erratically (such as stalling, performing loops, and chasing one another). at about 11:20am i stepped back outside to smoke a cigar and i observed the two aircraft in the n-nw area of my region. i continued to observe them over the course of smoking, where they left the area and returned a few times (flying directly overhead at this point). i then observed 3 white lights arranged in a triangular shape in the vicinity of the aircraft moving n-nw (more north, however) at a slow rate of speed as compared to the two aircraft, however the ufo appeared to be at a much higher altitude than the aircraft. at one point, the two aircraft appeared to circle and nearly collide with the object, at which point the aircraft continued in an eastern direction, then a southern direction, then a western direction until they moved far enough away that i could no longer hear the jet engines roaring. after approximately 15 minutes the two aircraft returned from a southern direction, heading due north, following the path of the ufo. the time now is 12:13pm on dec. 1 2017, and i no longer hear any jet engines or see any objects in the sky at my location.
