Off the top of my head, the official stance was the one I wrote! That Enoch was "taken" by God in that he simply had his life removed from him (to be resurrected on earth from God's memory at a future date) before he could be killed by evil men.
And Elijah was not taken to heaven by the chariots, he was dropped off on a mountain, from where he wrote some further Bible material (this is intended to explain why there's a writing from him after the time he supposedly was taken).
I don't have the time right now to back these up with WT citations, but that's what I recall.
