Stealth shapped silent object with no noise or vibration from north to south at slow sped and low altitude.This happened last winter while I was delivering papers for the Anchorage Daily News. I saw the same craft if not another that was identical to the first sighting on atleast 5 diffrent nights. Four of the sightings were in the same location and around the same general time of between 1;30 and 2;00 am. The fifth sighting was in a diffrent location and was about 45 minutes earlier . This sighting was due north of the usual location of the sightings. The craft was this night traveling south from north and was traveling at the same steady speed and about the same altitude. The speed I would judge was about 20 to 25 mph and was silent of noise or vibrations. If it was a painted craft it would be of a black color. It had white lights that strobed on the outer end edges of the rear part of the triangle with a solid burning white light in the front point of the triangle. It was a bit brighter I think than a normal landing light on a plane. I saw no green or red light as one would expect to see on a normal plane indicating port and starboard. The thing that was of intrest to me was that if it had been just another 45 minutes later the thing would have been over the same area that i usually saw it for the previous four times. As it happened this night I was running a bit early and therefore was in another part of town. The area of town is with housing additions and very thick wooded areas in between them. There i a mountain ridge to the east of the area about 4 miles away. To the south is the town of Palmer and the Matanuska River and the Knick River and the Knick Glacier and the rough and rugged Chugach mountains. Every time that I saw the caft was always the same altitude and speed and was traveling from north to south, no noise heard. I tried to take a photo of the craft but my digital camera was not the best in the world and is only 3 mega pixels and did not make it worth saving. I am 38 years old and have had experience as a Captain in the Oklahoma State Guard and my fathe! r was a police officer and Chief of police and I have had experience in observation from many points of view during my life and I have explained this to the best of my ability. My only explinations could be that it was either a military stealth craft operating from Elmendorf or that it was extraterestrial. Either way it was a true UFO for me.My telephone is 907 ((deleted)).((NUFORC Note: Witness indicates that the date of the incident is approximate. PD))
