******************************************************************************
The primary products of combustion for fuels are carbon dioxide (CO2),
water vapor (H2O) (superheated steam) and a little ash (leftover
carbon etc) for petroleum products. When the steam condenses it forms
microscopic ice crystals, which scatter light, causing a "contrail".
If you want to complain about something, start a thread about water
fluoridation and other additives to "improve" water quality. People
over 40 remember contrails very well, but fuel efficiency has made
engines that only make contrails under the proper temperature/
pressure conditions......
Most contrails disperse within seconds, but if things are just right
they feather out and can persist for 15 minutes or longer. If you are
anywhere near a hub airport such as Dallas/ Fort Worth then expect
lots of them on some days. Once again, ask someone who lived near a
major city in the 50's-60's, contrails did not kill them then and will
not kill you now.
The sky is falling! Chicken Little did say ?

FWIW - This is something I noticed very shortly after moving to the United
States. Airplanes just seem to leave a more visible, longer-lived exhaust
trail here than they do back home. I've noticed it almost everywhere I have
been (NY, TX, CO). I wondered initially if planes around here use a
different fuel mix than is normally loaded back in Australia.
I didn't notice it quite so much in NV/AZ or in FL. I don't remember if I
noticed it in CA or WA.
If you live near any kind of military facility, it's reasonable to expect
increased air traffic around now.
Well, these were definately STRANGE> STRANGE> STRANGE> not like normal
contrails. I'm very aware of the normals, I've lived here 11 years. These were
in patterns. Giant X's and crisscrossed lines. Very low in the sky, right
overhead, yet no sound heard from the planes and I had my windows open. They
hung in the sky for 3 hours. I took photos with my 35mm, will see if the turn
out.

I saw a "rainbow chunk", just floating in a vertical line the other
afternoon. I had forgotten about it, maybe I chalked it up to too much
fun in years past :)
