No Ray, not really. I was just being a smart alec that's all. Some pollution is necessary and some isn't. Like the story going on at the moment about Williamtown. About the chemicals in the fire fighting foam they used there for years and which the EPA knew about but didn't tell anyone in the local community. That kind of pollution isn't necessary, or at least the non-disclosure isn't and was probably illegal. I must admit I am a bit of a greenie but not to the extent that I can't appreciate and be impressed by those big smokey ol' jets. I think every little bit of pollution that can be saved is saving the planet for the next generations but in those days we didn't kow what we do now. However, back in the day we didn't know as much about a lot of chemicals as we do today. One of the solvents we used to use, Turcosolve has now been banned at least in Australia. That stuff was naaaassstttyyy. But we exposed ourselves to it every day because the job demanded that we did.
I have to admit I also am impressed by those smokey big jets of yesteryear with their water injection jet plumes billowing out in the sky behind them. Of course now that kind of pollution isn't acceptable anymore and the more modern turbofans in the BUFFs today aren't as bad. Nor are the CF-6s in today's KC-135s and nor are they as darned noisey as the JT-8s in our old 707s.
Adam, I'm not sure if those early BUFFs had APUs or not. If not then to make the aircraft more autonomous they may have had cartridge start on the 2 inner engines and then used bleed air from those 2 engines to start the others. Even our 707s when we originally purchased them didn't have APUs and depended on external air carts for starting. The Rays could tell us if all the fleet eventually got APUs or not but I do know that 2 aircraft at least did during my time at Richmond. This made them able to operate independantly anywhere in the world which is the whole idea behind an APU. Even piston engined long range aircraft like the B-29 and later derivatives and Martin Mariner and some Catalinas had small Briggs and Stratton or Tecumseh engines to drive a generator for starting or to provide power for servicing.
