Hi everyone,
Just a really quick question, what ever happened to that puffer machine that the TSA had before? You know the one, while standing in a phone booth, it shoots some air at you and sniffs for explosives. Is that not effective on non-metallic bombs? Also, what about using that swab machine that they use on bags on a person? Wouldn't that catch a bomb if it was rubbed on a person? Thanks everyone, I'm not really that up to date with all these machines and what they do, maybe someone can shed some light on the subject.
