In the aftermath of a major cheating scandal, the US Air Force is on a PR offensive. A CBS News crew recently toured a nuclear control center in order to shoot a segment for 60 Minutes. In a behind-the-scenes video released online, CBS Lesley Stahl talks through her experience touring the facility, revealing her surprise at the aging equipment (5.25-inch floppy disks are still in use) and relatively inexperienced staff. At one point, a staff member shows Stahl a still-used 5.25-inch floppy disk, highlighting the tech of the 70s that helps power the US nuclear deterrent.
