If you detach an EC2 instance from a virtual tape library and destroy it you can't delete the tape library any more. Even AWS support couldn't delete it. This is fine until you have 60TB of tapes online and are paying for it.
This is my worst nightmare. I had a situation like this where I was able to essentially ignore the entire AWS account and cancel the attached credit card. Amazon somehow linked this AWS account to my retail Amazon.com account and started booking my personal credit card.

Fortunately we found an EBS snapshot of the VM.
