Another pilot spoke to the NTSB about conditions that night.
He reported that above 14,000 feet, the visibility was unrestricted; however, he also reported that during his descent to Nantucket, when his global positioning system (GPS) receiver indicated that he was over Martha’s Vineyard, he looked down and “…there was nothing to see. There was no horizon and no light….I turned left toward Martha’s Vineyard to see if it was visible but could see no lights of any kind nor any evidence of the island…I thought the island might [have] suffered a power failure.”
He also stated, “I had no visual reference of any kind yet was free of any clouds or fog.”
