The next generation are eschewing bleed air driven pressurisation
and going to seperate supercharger systems. A lot of older
turboprops used this system as well as a small number of jets.
The 787 will have this system.

The B-707 had both Bleed Air and Turbochargers. We used the
Turbochargers most of the time. An engine bleed line spun a
turbine which then turned a fresh outside air compressor.

Yeah, that was the jet exception I had noted. You were lucky you
didn't have to breath the compresser section air in that thing!
The JT8 was OK AFAIK There would have been some fumes, but the
RB-211 is a
complete piece of junk. The Brits never could build an oil tight
engine....

Damn, I wish they would have let you design it. It would have been
perfect, uh.


Couldn't have done any worse...

From all that I heard, back when Eastern was flying L1011's, that is
putting it politely.


Still plenty of airplanes flying around with RB 211s as well.

In fact, I've been on a few of Lufthansa's 146's and they reek of the
**** as well.
