Absolutely brilliant, 'GenRadek'!! Good to see another level head in the discussion about 'chemtrails'.
Of course, the advocates of some nefarious 'plan' of chemical 'spraying' will recognize my User Name and likely jump to the conclusion that we are
'working together'....so I want to nip THAT notion in the bud, immediately.
This concept of 'spraying' from altitudes above what are considered nearly ground-level, as in crop-dusting, beggars logic.
(I apologize for typos I miss, I'm using my laptop right now...)
Just to re-iterate....I have written, and will continue to say that Commercial passenger jetsa CANNOT be in any way responsible for anything other, as
Gen pointed out, leaving a 'carbon footprint'....much as any internal combustion engine that consumes petroleum products will do.
(Yes, a jet engine is, in essence, an "internal combustion engine"...AND it burns a petroleum product. In fact, Aviation fuel, 'Jet-A', isn't
very dissimilar from kerosene....or Diesel fuel, for that matter).
Might surprise some people to learn that a jet engine isn't much different from the engine in their automobile....of course, big differences in
design, but the principles are roughly the same.....an internal combustion engine, using petro fuel, will have four cycles....suck in air, squeeze the
air, inject the fuel and ignite, then use that 'force' to provide the power.
We describe an axial, some might call it a 'rotary' engine (Jet Engines) as .... "Suck, Squeeze, Burn, Blow".
To make it use more words: Ingest the air, compress it, inject fuel and ignite it, and enjoy the resulting energy that results.
This is actually what happens in each cylinder of your four- or six- or eight-cylinder engine in your automobile. Each cyllinder is 'timed' to
provide its own 'oomph' to play well with the other cylinders, in concert, and to turn the driveshaft to make your car go. Jet engines use a more
advanced concept....but remember, a great many large airplanes were built using the same principles that are in your car engine before jet engines
were invented.
Point is, just as your car engine emits exhaust gases, so to jet engines. AND, these exhaust gases come out hot! Picture, if you will, a very cold
and damp morning, when you start your car. Do you see condensation coming out of the tailpipes?? Now, make your car travel at 500 MPH, and you will
make contrails!!!!
Congratulations for completing the first lesson 'Internal Combustion Engine' science. Don't forget to sign up for 'Meterology: 101'....
(there is a linkage between the two...but, it's best if you've a good understanding of Physics, first)
