A thumb drive containing personal information of Portland International Jetport employees and vendors, as well as pilots and flight attendants, is missing.

The information of 950 people who carry jetport badges was transferred between two computers with the device on May 23, according to WCSH-TV, media partner of the Portland Press Herald.

Jetport officials do not believe the thumb drive was stolen but, as a precaution, have notified of all the people whose information is on the thumb drive, WCSH said.
