Interesting. To me, "bootstrap" means something else (plant startup).

Any stories about the guy that got forgotten in there/fell asleep and ended up being unintentionally part of the project in a way he never intended? Hell, if there isn't one, make it up.

I seem to recall old shipbuilding tales about the worker that got welded in behind a bulkhead due to being hungover. A cautionary tale indeed!
