    • /u/saabstory88: It's funny that you should mention that engines, fuel lines, and a thrust structure have never been used like that before. In fact, it was on the original incarnation of the Atlas that used exactly that technology. In the stage and a half configuration used by the Atlas missile, SLV series, and Atlas I and Atlas II, they dropped the whole outer booster structure, and cut the fuel lines mid flight. So this latest "Evolution" of the Atlas will actually use a staging method seen on the very first model. For reference: http://www.b14643.de/Spacerockets_2/Diverse/Atlas_MA-drive-system/index.htm
