Well--That makes a bit of sense, thanks, Robert! I'm skeptical that supply
will remain uninterrupted, and it seems to be a pretty optimistic theory
that we won't see a supply interruption at all... but it's nonzero I guess,
and if we're still getting them as of now, that's something (I didn't
realize there were more in the delivery pipeline for this year).
That plus an Aviation Week article sent to me off-list that claims a
2.5-year development cycle for a replacement engine by Rocketdyne (which
also seems pretty strongly optimistic) at least seem to be two possible
paths through the drought.
Wonder how they'll play out.
