I agree, on a twin you have twice the chance of an engine failure ----- which in the case of many twins means you are going down if fully loaded and the field you are going to land in will have to be longer as your approach speed will be higher. Slightly far fetched, but I would rather be in a PA28 with a dead engine going for that small field in Kent rather than a Piper Apache with six occupants and full fuel and a engine failure on the left !!! Obviously does not apply to the PC12 versus King Air argument.
