[Elmo]

no after reading this little discussion i decided to reread the akallabeth and stumbled upon this passage Mariners 'who by some fate or grace ir favour of the Valar, had entered in upon the Straight Way and seen the face of the world sunk below them, and so had come to the lamplit quays of Avallone, or verily to the last beaches on the margin of Aman, and there had looked upon the White Mountain, dreadful and beautiful, before they died.'

I took this to mean that they were killed when they reached the undying lands through no fault of themselves.
