Not a true 707 but rather the REAL 717.. when I went through Instructor school on the KC-135 we did 2 engine out (same side, in idle) approaches and go-arounds. Once we had demonstrated that we did 3 engines in idle and a single engine (sort of) pattern with an approach and go around. Gear when you were assured you had the field.. flaps 30. On the go, MAX thrust, lots of rudder and gear up with the slightest hint of positive rate. Milk the flaps back up SLOWLY and climb out. Not easy but did not require a superman.
Long time ago...
