I hadn't known that. Is that a center engine? Intuitively it seems like more would be better so that in the case of that engine failing you could use the other engines to push up and maybe light another engine. Of course, if there's two engines and one fails, it's going to tilt. Same with 3, though to a lesser degree. 4 engines lessen it even more, etc. etc. Or maybe they can detect a bad center engine on descent (it doesn't light or flame is detectably not the right) and then go to outer engines. Or drop it in the ocean. Hope there aren't people on that one.
