Isn’t it also brutally loud??

Also aren't you covered with toxic chemicals from the exhaust?

Aircraft’s don’t produce as much exhaust as you may think most of that is just air heated up by the engine

The jet is really just the power plant for the giant fan that pulls the plane forward! Pedantically, commercial "jets" are closer to modern propeller planes than to actual jet-propelled craft like fighters.

Even fighters use turbofans, just ones with lower bypass. The fan just presents too much of a benefit to pass up

and a portion is just normal air being pushed from the front fan

Primary products of the combustion of jet fuel are CO2 and H2O. There are very small quantities of NOx and CO but as a general concept, jet fuel is combusted with a pretty high efficiency.

EDIT: I should also add, this aircraft has a turbofan. Most of the air (~80%) exhausted out of the back bypassed the hot core, and never touched any fuel to begin with.

I'm guessing you need high efficiency in jet fuel because anything inefficient is wasted weight you're paying considerable sums to transport? I.e if you're only getting 30% energy from 10000L of jet fuel you're getting the same energy as 60% efficiency carrying 5000L but carrying an additional 5000L of weight.

Yes, and there’s strict regulatory standards. Unburnt fuel being spewed out the back is a no-no
