As it was I am a bit of a history buff the military type. I came across the Davy Crockett missile on display at the Ordnance Center and Museum. The first thing that came to mind was this doesn't pass the common sense test, at least not for the crew who launched it. If you were unlucky enough to serve your country with this thing you might find yourself giving your life for the cause. I think you had to ready a foxhole, fire the missile and kiss your behind goodbye.
I don't think the crew loved this thing either. They abandoned one in Texas. That crew passes the common sense test.

The next example is the HUGE BOMB called the Bunker Buster. Aberdeen is a Research and developing facility. Researching, developing and I guess testing this bunker buster is what they did. It was designed to Bust into U-Boat Pens (Bunkers). This thing set records for hugeness. So huge in fact they never had a bomber to carry it at the time. They just weren't capable of carrying something like this so massive in WWII. It passed the common sense test to design one of these. We didn't understand the times back then. In light of it all it still makes the list.
