Whilst the chances of an engine failure are slim, survivability also depends on the surrounding area. It amazes me how many airports have housing/buildings so close to the approach/depature path. A clear path on the runway heading will increase our chances rather considerably until height has been gained.
As an aside, I remember a fatal crash in the 90's where a pilot suffered engine failure. ( I am not sure if it was EFATO).He set himself up to land on a road in an industrial estate I believe. Engine picked up, he attempted to climb and then the engine failed again. He unfortunately crashed and lost his life. I was always taught, if the engine has gone and you are committed to a forced landing, execute it accordingly. If it picks up, never, repeat never try to climb away!
