If it hasn't been retrofitted out, then it's still in use today. That sentence would only be incorrect if the new solution was retrofitted on all aircraft.

  > is so elegant it’s still being used today I think it's the "so elegant" part that's wrong. It's not still being used today because it's so elegant. It's still being used today because the old helicopters haven't replaced it.

    I think elegance has to do with the technology of the time. Some clever design that is cheaper/better than you would otherwise think possible given the era. There are probably many elegant aspects to Roman aqueduct engineering, but they would still get replaced with modern materials during a retrofit.
