A Yankon, South Dakota man reported to have seen strange lights in the sky over a period of four days that started on January 3, 2013. The witness said that a light similar to a police light ejected smaller lights. The testimony of the witness was filed to the Mutual UFO Network (MUFON) on January 6, 2013.
According to the witness, the sightings started on the night of January 3, 2013 around 10:15 PM. He noticed the strange lights that look similar to the police lights flying around. The part of the sky where strange lights appeared is a busy flight path. The witness can see planes and helicopters flying by on any day at any time. However, he was certain that the flying strange lights were not coming from a plane or a helicopter.
The witness saw a smaller object ejected from the larger one. The flight trajectory of the smaller object was on parabolic curve toward the ground.
The object then disappeared behind the trees and houses. Then, a herd of cows on a mile away somewhat freaked out briefly. Fortunately, no cow was harmed and no crash happened. Seeing all of these, the witness thought that there may be more of them. So, he started to look around at the sky and spotted about four or more of them but they are either smaller or at higher altitude than the first one.
On the following nights, the witness noticed that they seemed to increase in number every night. According to the witness, on Thursday he saw about three or four of them, on Friday they went up to six, Saturday went even higher at 11.
The witness saw a UFO coming closer to the ground and he saw that it was similar to a shape of triangle or stealth fighter aircraft. However, there are no military bases near the area where he saw the strange lights.
