A group of workers witness a strange light in the sky, which accelerates and departs vertically at very high speed.Telephoned Report: A 57-year old man reported called via the Hotline to report that on Friday, September 12, 2014, he and a group of fellow co-workers were standing at a jobsite, when one of them became aware of a rapidly approaching light, which appeared to the witnesses to be unusual.One of the witnesses, a former U. S. Navy sailor, trained in aircraft identification, suggested that the object might be an approaching helicopter, but that explanation was rejected by all the witnesses, given the apparent absence of any sound coming from the object.The object slowed, and then suddenly accelerated, appearing to the witnesses to depart vertically at very high speed.The caller declines to submit a written statement about the sighting, expressing fear of reprisal from the U. S. government.((NUFORC Note: Witness elects to remain totally anonymous; provides little contact information. PD))
