Thanks for that Captain Groper.
As he lost the engine say 25% into his flight he would have landed at WSSS having eaten a small way into his diversion fuel. It is acceptable practice under Eu ops to throw away alt fuel if desination has more than 1 runway. (do not know about Singapore regs). I know the 747 from LAX divided the camp as to whether it was wise, I wonder how the camp would divide on this one?
