the light was very bright and had a very large vapor trailI was driving from Fairbanks to Eielson AFB about 28 miles south of Fairbanks at approximately 2:30 -3:00 PM and I noticed a flash of light in the southwest sky. the light resembled a flare shot from a flare gun but the flare was on a downward projectory with a vapor trail. There was no indication of an upward projectory and the whole incident was much larger than a flare incident. after the light burnt out, the vapor trail was still very much obvious. this also indicated to me that the object was much bigger than a flare from a flare gun. this display took place in what I thought might be an Army training area near Delta Junction which is also south of Fairbanks.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
