Bifurcation of the trails is due to the duel thrust emissions from the high-bypass turbofan engine. Only 15% to 20% of the air intake goes into the engine combustion chamber to produce the water vapor necessary for a contrail to form. Remarkably, a whopping 80% to 85% of the thrust that exits the engine is NEVER subjected to the combustion chamber. This means that almost all the thrust in INCAPABLE of producing a contrail. Furthermore, the 15 to 20% that is sub
