Personal records for every Navy and Marine Corps aviator or aircrew member who has logged flight hours in the past 20 years have been posted on a public Navy Web site for the past six months, compromising more than 100,000 Social Security numbers, the Navy Safety Center announced. Investigators are working to determine how the records landed on the Navy Safety Center's Web site, which officials shut down Thursday after a member of the public reported finding the full names and Social Security numbers posted.
