I was in the "hole" in federal prison. Got sent to the "hole" because a guard found my little steam roller (a playing card rolled up and taped. then the metal eraser holder from a pencil for the bowl. pinch one side down almost flat- slice a hole in the card tube and insert crimped end of metal in tube.worked great!)
I remember hearing two guards talking about it down the hall. I assumed it was a small plane and went another week in the dark.
When I got out of the hole and released back into the housing unit, one of the buildings falling was on tv. HOLY SHIT! An inmate looked at me and realized I just found out what happened. He filled me in on the details.
The prison made a disaster plan. They said they got enough plastic and duct tape for everyone to tape up windows and doors should there be a chemical/biological attack. they also said that the lake nearby could be purified for drinking water should it come to that. Needless to say, it was a fucked time to be locked up!! (I guess they are all bad times)
Anyway, I got out three months later and have been glad to be free.
Peace.
