They've re-engined a little over half of their 727s, with Rolls-Royce
Tay 651-54 engines.

Considering that there are *still* a few DC-3s in service, I don't
think UPS should have much problem squeezing more life out of these
aircraft.  Northwest is upgrading many of the DC-9s, some of which
are even older than UPS' oldest 727, and expects them to be flying
with them for at least another 15 years.

That's the Valsan conversion, two of which were done (both for Delta)
before the company went under.  There was some discussion about the
project in this newsgroup a while back -- check out the archives,
available for anonymous ftp on (in /chicago/airliners)
and on
