I accidentally brought a knife on the plane. My ceramic knife went right through security And before I realized that TSA had waved me on. Was only a small night and it was for survival. I'm not crazy Not afraid to the plane going down but my every day carry Consist of over 100 pieces of survival gear on my person at all times As well asFor different ways to start a fire. And it's all completely concealed. It's only there so I can fare a bit better than Tom Hanks And I won't have to relying on some FedEx packages and a volleyball should the plane go down on a desolate island. And of course I don't leave home without my slingshot So you better believe that was with me.
