EMIT,

Quite correct, I hadn't thought thru the implications of reducfing lift on the unaffected side. I'd guess night, zero G maneuvers and instructing the PM to shutdown the engine would earn...

No, it doesn't, the efflux is too far aft, depending on specific design. It's controllable in sim profiles on the Challenger and Global types bug more yaw that simple engine failure. I can't say as...
