From downwind, 50 feet and 130 knots its going to take a very talented and wide awake driver to turn into wind from an unexpected engine failure. From experience I know that it takes a second or two to even have the brain admit that the engine has failed, despite the evidence in front of you, and only then will the reflexes take over. I would not even try to turn around, at 50 feet and 130 buttons you will not make it to an open spot you just flew over even if you are expecting it. It all sounds good in theory, reality bites.
