- At the rear of an Atlas there are three engines, in a row. The outer two
- are mounted on/in a short structural ring that forms the lowermost part of
- the outer surface of the Atlas. At staging, the ring falls off, taking
- the two engines with it. The center engine continues to burn. Fuel feeds,
- electrical connections, etc., are disconnected as the ring separates.
- I believe the outer engines shut down just before separation.
