apr 19, 1917 - America upgraded the "flying bomb" to the kettering bug.
Development of the Kettering Bug, formally called the Kettering Aerial Torpedo, started in April 1917 in Dayton, Ohio after the U.S. Army asked inventor-engineer Charles F. Kettering to design an unmanned flying bomb with a range of 40 miles. Kettering assembled his team, including Orville Wright, and worked on this project. However, the completion was to late, and did not fly into war.
Benefits: the benefits of this is that people were curious enough to keep looking into this instead of thinking, oh, i guess i'm stuck with this.
Costs: people are putting their curiosity to war efforts instead of putting to a more effective use. this results in bloodshed and destruction of architect and other such significant places
