3 engines? 4 engines? 2 engines? BLACK BOX, in order to do commercial service, an airliner MUST be able to fly AND lift off from V1 with one engine out. It doesn't matter the number of total engines on the craft.
The problem was that when the engine left the wing, it severed hydraulics lines on that wing. That caused all the slats/flaps on that wing ONLY to retract. The left wing entered a stall and the plane began to roll. The crew then found themselves in a unique situation that they had never trained for; this event even suprised MDC, as they did not design slat/flap locks into the DC10 until after this accident. Giving more power to the engines would only have compounded this problem.
If this occurred at cruise AND the wings were clean AND it did not take all three hydraulics systems with it, this should have been survivable.
