Bright round White object sited in Rush County, Kansas.We saw a very large Bright White circluar object with small green and red flashing lights, that remain stationary for approximately 5 minutes. During the last 2 minutes green and red lights ceased- and then simply vansihed. Immediately following disappearance of object, area swarmed by 6-12 Aircraft.((NUFORC Note: Witness elects to remain semi-anonymous. Military facilities probably would not launch 6-12 aircraft, in order to identify an anomalous target. PD))
