 The radar contact is believed to have been made just after 9.30, believed to have been made about 17 miles west of Martha's Vineyard in that Gay Head area, and the aircraft was believed at that time to be down to about 2,000 feet. Footnote, bottom of the page, reminding again that there are two ion air witnesses who say that they saw and heard a small plane 20 to 50 or 60 feet off the water at about that time, that is 9.30 to 9.30.
