"turning left by turning right through 270degrees."

Not sure if you're joking or not.

There is at least one real precedent for this, e.g. United Airlines UA232, McDonnel Douglas DC 10-10, uncontained engine failure in the tail mounted engine (caused by a latent manufacturing defect) led to the loss of all three hydraulics systems on the aircraft.

"using the throttles, they could control one axis of motion at a time. They were able to raise or lower the nose by speeding up or slowing down the engines, and they could make unstable but manageable turns to the right by slowing one engine down and speeding up the other. However, they could only turn right, meaning that to turn 60 degrees to the left, they had to turn 300 degrees to the right. "

Of 296 passengers and crew on board, there were 112 fatalities.
