Sorry, Brooks: As a former crew member on TWA 747's, I can say from personal experience that we sometimes flew with that fifth engine in place, to get it where it needed to go. TW, for example had a maintenance base Paris, and we sometimes ferried the engines there. If you could see the front of the engine, you would see that it had a very large spinner mounted on the shaft. This was to limit some of the airflow through the engine, to avoid overspeeding the engine. For the same reason, we kept our speed down to about Mach .78.
