I've just often wondered why American flying machines, both civil and military chuck out so much muck when you compare them with machines built in other country's.
I knew the DC-8 and 707's were smokers or at least certain variations of them were. I never knew the prototype threw out so much sh!te though. I think the most renowned smoker of them all has to be the good old Convair 880!
I suffer from paranoid amnesia. I can't remember who I don't trust.
All the early 707s/DC8 series were water wagons - I remember seeing a
100 series 707 take of from Lagos on a particlualrly hot day and the
balck smoke hung around for hours.....even the early JT8Ds smoked
like a russian factory worker.
Oddly enough that might actually be healthier than today's engines. At least if you inhaled that lot, you'd cough and eject most of the crap again. With today's engines, the carbon particles are so small, you dont cough, you just take them into your lungs, so my aircraft propulsion lecturer said a couple of years ago :-&
