    Basically all of our safety devices came about after things went horribly wrong.

    Any chance you might be able to put a date on that memo? If it's prior to 1947, you could have an interesting tidbit of history there showing an early use of the term bug to describe an engineering flaw.

    If only he knew what was coming, but the technology at the time was different.

    The "bug" story I am aware of is the first major computer built for the end of WW2, maybe used for D-day plans etc.
    The maze of electric mechanical relays used would fail because of bugs seeking the warmth of the coil heat. Thus the term of "getting the bugs out". ..........fact or Urban legend?

    Transmitters used to use thyratrons in their power supplies and they are mercury based so they glow ultraviolet. That glow drives bugs crazy, do you know what happens when a nice fat but goes splat against a tube that is running at 4-500 degrees?

    It lets the smoke out.

    I have a kid's book about some of the crazy ways things were invented by Ira Flatow. It's a really good book, simply written, with some hilarious stories.

    I believe the "First Computer Bug" story that JUGHNE related is pretty accurate. The book has pictures of the engineer/operator's logbook entries detailing the failure, finding the bug (a moth) beaten to death in some relay contacts, and the actual moth taped to the page.

    Great book. I'll see if I can find it and snap a pic.
