Most aircraft manufactured for WWI & II etc were for killing people, look at percent of total numbers. Why did we beat the Brits, cause we had a lot of settlers with guns who were good at shooting game and vermin. Watch Braveheart ... Wallace and friends had a bunch of hammers etc.
BTW: don't forget the first ... Cain killed Able.
Also, I want to thank my good internet buddy @MPhillips for telling me about this "fun" Other Stuff section of this here board.
