Many obser­vers of the past two deca­des of covert aero­sol geo­en­gi­nee­ring adopted the term “chem­trails” to descri­be unna­tu­ral emis­si­ons and trails ori­gi­na­ting from mili­ta­ry jet engi­nes.  If the term Chem­trails ori­gi­na­ted at the DoD we could suspect the term came into wide civi­li­an use when a cadet or ins­truc­tor repea­ted it so often that “Chem­trails” was adopted by civi­li­an obser­vers to descri­be unu­su­al jet air­craft contrails.

To their cre­dit, the Oxford dic­tion­a­ry pro­vi­des an accu­ra­te descrip­ti­on of chem­trails even if they fai­led to list the US DoD as the ori­gi­nal published source.

Ori­gin:  1990s: blend of che­mi­cal and trail, on the pat­tern of con­trail (Source)

In ety­mo­lo­gi­cal terms, the ori­gin of a word is very important.   Regard­less the inten­ded defi­ni­ti­on, histo­ry cle­ar­ly shows the term “Chem­trails” ori­gi­na­ted at the US Depart­ment of Defen­se as the title for a Che­mis­try manu­al used at the Air Force Aca­de­my cadet trai­ning pro­gram in the ear­ly 1990′s.  Two edi­ti­ons of the “Chem­trails” manu­al are known to exist – A 200 page ver­si­on for the 1990 Fall class and a 232 page ver­si­on for the 1991 class. The cour­se title “chem­trails” was so popu­lar as to be adopted by the DoD for at least two aca­de­mic years (1990−1991).

About the Chem­trails Manu­al Cover

• The Air Force Aca­de­my Chem­trails manu­al cover shows a  fla­me from a  Bun­sen bur­ner that appears to be pro­du­cing two “trails”.
• The title of the manu­al “Chem­trails” is prin­ted bet­ween the two “trails”.
• Con­side­ring the inten­tio­nal gra­phic depic­ting “trails” it’s pos­si­ble the Bun­sen bur­ner repres­ents a jet engi­ne pro­du­cing “che­mi­cal­ly” indu­ced, per­sis­tent contrails.
• A Bun­sen bur­ner is a com­mon pie­ce of labo­ra­to­ry equip­ment that pro­du­ces a sin­gle open gas fla­me  which is used for hea­ting, ste­ri­liza­ti­on, and combustion.
• A test tube fil­led with a liquid is emp­ty­ing con­tents into a flask.
• The remai­ning gra­phic appears to be a che­mi­cal repre­sen­ta­ti­on for “metha­ne” (CH4).  Sin­ce Natu­ral gas con­ta­ins most­ly “metha­ne” it’s pos­si­ble this sym­bol allu­des to the fuel pro­vi­ding the fla­me to the Bun­sen bur­ner. (Natu­ral Gas)

Method:  An inter-libra­ry loan from the Alachua Coun­ty main libra­ry yiel­ded a micro­film copy of the 1990 Che­mis­try 131 Manu­al used in trai­ning by the US Air force Aca­de­my.  The len­ding insti­tu­ti­on was the Wil­liam T. Young Libra­ry at the Uni­ver­si­ty of Ken­tu­cky as shown in the label below.

The micro­film was in accep­ta­ble con­di­ti­on, howe­ver the 1990 Chem­trails manu­al was scan­ned in 1992 under less than opti­mum con­di­ti­ons from a used hard copy in less than good condition.

The Alachua Coun­ty Libra­ry equip­ment was used to scan each of the 200 pages to digi­tal *.TIF files.  Pho­to­shop was used to opti­mi­ze each image to the smal­lest file size that would per­mit ade­qua­te reso­lu­ti­on for on-line vie­w­ing.  Each image was impor­ted to a Micro­soft Word page whe­re the com­ple­te manu­al was saved to  a 30 MB  PDF file.  (Por­ta­ble Docu­ment File).

NOTE: A second edi­ti­on of Chem­trails (232 pages) was published for the Fall 1991 class of Air Force cadets.
