In the wake of the deadly terror attacks in Brussels, police in New York were deploying specially-trained dogs that can pick up the scent of a bomb in the air. These so-called "vapor wake" dogs are trained not only to sniff out bombs in bags, but to pick up the scent or vapor of a bomb as it wafts through the air. Once the dog catches the odor, he can follow the plume or bomb vapor up to the length of several football fields. Kimberly Cheng reports from LAX for the KTLA 5 News at 10 on Friday, March 25, 2016.
