Minimum vs. Maximum Security: we fly on a wing and a prayer
on August 8, 2017
These were primarily good for making sure zippers on duffel bags and luggage didn't fail and spill contents. Check YouTube: there are so many ways for determined thieves to pilfer things, and not even be detected (ball point pen used to separate zippers, then putting zipper right again---just one method). I sort of doubt people are often bold enough to swipe things from bags stowed in the the upper luggage racks on the plane, but...if so, this would at least slow 'em down momentarily.
