"Chemtrails" have been around since modern aircraft were invented. World War 2 planes would create "Chemtrails". Even planes that have propellers
create "Chemtrails". It all depends what altitude the aircraft flies at, actually, its more about what temperature the air is around the engine. They
can even occur on the ground. They usually only last for about half an hour. Maybe longer in cold weather. Chances are planes are either flying at a
lower altitude, or do not generate enough heat to create "Chemtrails".
There are two types of these trails
1. Condensation from engine exhaust (These are what you know as "Chemtrails")
2. Condensation from decreases in pressure (Minor contrails created from lift being generated by the aircraft)
Condensation from engine exhaust
"The main products of hydrocarbon fuel combustion are carbon dioxide and water vapor. At high altitudes this water vapor emerges into a cold
environment, and the local increase in water vapor can raise the relative humidity of the air past saturation point. The vapor then condenses into
tiny water droplets which freeze if the temperature is low enough. These millions of tiny water droplets and/or ice crystals form the contrails. "
Condensation from descreases in pressure
"As a wing generates lift, it causes a vortex to form at the wingtip, and at the tip of the flap when deployed (wingtips and flap-boundaries are
discontinuities in airflow.) These wingtip vortices persist in the atmosphere long after the aircraft has passed. The reduction in pressure and
temperature across each vortex can cause water to condense and make the cores of the wingtip vortices visible. This effect is more common on humid
days. Wingtip vortices can sometimes be seen behind the wing flaps of airliners during takeoff and landing, and during landing of the Space
Shuttle."
Here is some evidence to support your fuel theory.
" 2013-2014 study jointly supported by NASA, the German aerospace center DLR, and Canada's National Research Council NRC, determined that biofuels
could reduce contrail generation. This reduction was explained by demonstrating that biofuels produce fewer soot particles, which are the nuclei
around which the ice crystals form. The tests were performed by flying a DC-8 at cruising altitude with a sample-gathering aircraft flying in trail.
In these samples, the contrail-producing soot particle count was reduced by 50 to 70 percent, using a 50% blend of conventional Jet A1 fuel and HEFA
(hyprocessed esters and fatty acids) biofuel produced from camelina."
