When I replied to this thread[0], with this comment[1], both the comment I was replying to and my comment were talking about trijets in the abstract, not MD-11s in particular, and the current year, or perhaps as early as the 1990s, but definitely not as early as the 1960s. Several comments, including yours, seem to have misconstrued that to mean I think the MD-11 in particular could be retrofitted into a twinjet. That's, uh, wildly mistaken, and not something I've ever claimed. I just think trijets in general are a design dead-end. Again, that doesn't mean it didn't make sense in 1960s when the DC-10 was being designed.
