Travelers often question whether the scales airlines use to weigh checked bags are accurate. To see how the equipment stacks up to scrutiny, reporter Damian Trujillo tagged along on a "scale inspection" today at Mineta San Jose International Airport. "They can't be a tenth of a pound over or under, or inspectors will shut them down.” The scale Atwood red-tagged required some recalibration to bring it back up to code. By tonight, all scales at SJC are accurate, with inspectors hoping to at least take that weight off the shoulders of passengers.
