Reminds me of doing a site survey at a somewhat remote cell tower, prior to performing some expansion work. Was told there was sensitive, classified military communications equipment inside the shack at the base of the tower, and had to perform work carefully around it lest we damage something. Couldn't tell me what kind of vibrations etc I had to keep my equipment under, as those details were classified. While I was there, I watched a Verizon tech show up to fiddle with their equipment inside the shack, which happened to have the door frame somewhat out of square. The tech's solution to getting through the tight security door? Unlock it, then smash on it with a sledge hammer until it came loose and swung in. I guess the fragility memo hadn't gotten down the line to the service techs.
