Oh, I never considered that:D It is an interesting use of materials, but seems unnecessary. I was thinking about a scenario in which an assailant would attack an actual soft spot in an airport. That did not happen. That is the part that surprises me ( and I am glad I remain surprised ). Then again, you start reading about new and exciting ways of detecting guns and you start wondering if that is basically trying to fight an old war.

<< My wife says it’s a wonder I’m not on the no fly list.

For better or worse, my work almost guarantees that I will be looking for mildly interesting subjects so I am likely on some sort of grey list ( no idea what IC would call it internally ). No 'no fly' list yet, but these days it only takes being extra rude it seems[1] so these days that list is a major inconvenience, but the signal it generates is less useful:D
