Need more time
>>60 seconds of a three-letter agency knocking at the door.
This reminded me of a custom spring loaded security door mentioned in "The Construction & Operation of Clandestine Drug Laboratories".
Might give a person a lot more time to destroy drives... as long as they can get into the room and close that door.
An auto-destruct button would certainly be cooler but.. I really liked the diagrams for that door too.
