Noticed loud aircraft noises outside and saw 2 aircraft rapidly zig/zag or figure of 8. watched for ~15seconds before out of sight, but noticed flashing white, blue, green, red lights like a star but brighter in same region aircraft were seen. got in car to go to top of ridge to observe as no towers or other sources we could think of for source. car acted very strangely, would not start, was turning over well and would continue to turn over without hand on key in ignition. newer (2014) vehicle, well maintained, kept in heated garage never with battery issues. took different car which did start. on stop of ridge observed object through binoculars, however still appeared too distant to see details. could only notice rapidly flashing blue, yellow/white, green and red lights. did not appear to be moving relative to horizon or stars. no further aircraft observed. returned home and noticed identical object/light pattern to south. have never witnessed similar event in past, nor the aircraft that low in this area. also have never seen pattern of flight aircraft were preforming. continued to check but lights remained present for 2 hours.
