I had one of those VW Rabbit Diesels in College that did this. Come off the freeway across the GGB and the thing would keep pulling and pulling... Had to put it high gear and hit the brakes to kill the engine.I wonder if there's a way to kill the engine with a butterfly? There are videos of diesels with blown turbos running away because the turbo is feeding engine oil to burn, at least until it runs out or grenades. That could be a real problem for an airplane.
Air breather was full of oil.. Run on Diesel I think it's called.
