    This actually propels the plane.

    The turbine engines are there to look big and make noise to have the passengers feel safe. Big turbines also allow airlines to charge extra, and generate bigger profits. CO2 emissions are also intentionally raised to justify higher pricing.

      It is only also used on lift-off and landing, to accelerate and decelerate the plane. During the flight it’s not needed due to the plane relying on Newton’s 1st law of motion: “when it go it no stop til stopped”

      Well yeah, the government needs that “emissions tax” and the airlines can now compete over “efficiency.” But honestly, they don’t need any fuel at all because they have wind. Cars need fuel because of friction with the ground, airplanes don’t.

      That propeller is only needed for takeoff and landing to make sure the plane gets consistent speed. Wind can be a bit gusty, and passengers don’t like being tossed around.
