Manhattan Project
the development of the atomic bomb, the best-kept secret of the war, even Truman didn't know about it when he became president; it was called that b/c it was mainly being worked on at Columbia University in Manhattan
hope this helps!

Hmm. The impact would've been HUGE. Because you're coming face to face with the person you're going to KILL. Sometimes people aren't really affected by death and that's mostly what i think that THESE people are. (For the evidence, I can't see the text but i'm sure you can do something!)
