Well, this has got lots of small bits & pieces of intricate details I was anticipating to read about. I will note her tail next time to confirm it is a G2, from another spotter I got to know that she had been running her 2nd or 3rd t/o that day hauling Superbowl traffic. I was wondering how a modern jet like a Gulfstream could put out so much black smoke, when I see B744 & MD11's not doing this during heavy t/o's.

What a lovely photo. I can remember being a young co-pilot in those days and, when given the take-off with the complicated SID from runway 31L, from Idlewild as it was in those days, being advised by the captain not to worry, the departure was easy. All you had to do was follow the smoke. It was a calm day...and he was right!!

The Olympus produced a bit of smoke but nothing like that shown in post #18.

I've often wondered if JP4 produced more smoke than JET-A1 (JP1).

We used it a bit on the Electra when operating from US air bases.
Mind you the Electra makes enough smoke any way.

Another really smokey aircraft was the Convair 990A. They used to leave a trail that could be seen for many miles on a calm day.

Wasn't that a RR Conway engined 707 in post 18?

I doubt it, Storm....
The Brits couldn't afford those nice big Havana stogies the Yanks smoked.

Negative.
AA used Pratt&Whitney JT3C-6A water wagons.
Much smoke.
Just like you see.
