The outline/shape of the disk and the lights underneath were very clear but the disk seemed colorless!Out for evening walk! SURREAL! Partial cloudy sky... Moon behind us.... Out of no where, these flashing lights [red, amber, blue/green] appear in the sky, and this craft starts doing cartwheels, and other maneuvers! It was at the lowest level of clouds but seemed no more than 300-500 feet above our heads! Going straight [NE], then immediately turning left; goes a short distance and comes back to the right doing unbelievable wobble type moves while going in UNPREDICTABLE directions! VERY FAST! Then takes off going W/NW and disappears into clouds! As it takes off doing wobbly type maneuvers and lights flashing clear & bright a jet begins to streak across the shy from the direction the ufo came from and is on a straight line path towards this space craft but it never catches-up! My wife and I both saw this very clearly! Her eyes are MUCH BETTER than mine..... I saw one craft [ship?] that was about the size of the moon and somewhat changed shape [round to oval] as it performed half-cartwheels, left to right. My wife saw this and a smaller craft interact.((NUFORC Note: Source of the report elects to remain anonymous; provides little contact information. PD))
