Think you'll find the term "water wagon" mostly applied to the B707-120, -138, and DC8-11, -12 aircraft .... since they're the ones which required water/methanol injection to boost T/O engine thrust .... and is what also resulted in their signiture heavy smoke effects on T/O. The later B707 and DC8 models could, apparently, be water injected too .... BUT .... seldom were .... if ever .... so far as I'm aware. BUT ANTWAY .... what you've previewed here, so far, looks "ABSOLUTELY GREAT" .... and is "A CREDIT TO YOU" Paul Mark C AKL/NZ

The 320 is listed as a water buffalo on the tech sheets, but as you said, they probably bid not need it at most airports. I used to see them regularly, but cannot remember how they smoked now. TAP 727-100's were never modified, so did quite a good impression of 720's by the amount of smoke that they left. |Nothing rivals the Convairs though Attachment DeletedTAP 727-100 Attachment DeletedNot for getting these. KC-135Q back in the early 80's at the Hall. Attachment DeletedCaravelle 10's could also smoke well. Air Mali on lease to CTA, again early 90's. Paul

I have some more info taken from a Pratt & Witney (FAA))Data Sheet (4A26) which list all the JT-4A models, and they are all marked as Dry, so no water wagon. Compare that to the zillions of JT-3C models on Data Sheet 4A21, and they have wet and dry listings for each engine type. So no water on the 4A models. Paul

That sounds about right I think the wet option was mostly relevent to high weight or otherwise field (and maybe terrain) restricted operations .... in order to get that bit extra thrust which the water/methonol injection system promoted .... where required/necessary. Mark C AKL/NZ
