    When a plane loses power this lowers into the airstream to make brrrrrrrrrr sounds to keep the illusion of engines.

    Edit: I feel I should expand on this. Like a hockey card in your bmx spokes.

        I tried to find a Scary Go Round archive with the whole subplot of the communist robots having a party at the bus station and fucking the buses, but it is too old to be available, I think 😢

    Should’ve added the NSFW tag on this, I was on an air field and every airplane in the area had there’s pop out…. Lots of fluids everywhere.

    When an aircraft loses engine power, this automatically pops out. As in this scenario, not all instruments are powered and one has only one shot at landing, this is to assist in the expected imminent landing; it operates something like a curb feeler on a car. When you hear the propeller impacting the runway, you know that you’re probably too low.

    ( David Attenborough voice) After the passenger jet has migrated to its fertility grounds it is ready to give birth. Unlike human babys, the passenger jet leaves the mother sideways. This way it can gather some draft before its heavy seat area touches the air. At this point, The mother needs to hover near enough to the Earth’s surface not to endanger the newborn fall, as it’s propellers are far from fully developed and can’t sustain proper flight yet.

    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.

      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.

      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”

    It’s a tactical windmill that can be deloyed to cause cancer in the overflown area. And kill birds drones.

    These deploy in case of total engine failure to provide enough thrust to get the aircraft to the next airport.

      Yeah, an Auxiliary Propulsion Unit. Seeing one deployed is pretty normal, but when an aircraft has two or more out at the same time, you should be leery of deeper problems with the main engines.

    As the aircraft moves through the air, this turbine harvests some of the relative difference in airspeed to convert it to energy that is then used to jam the radio frequencies of all the drone birds in the area that would otherwise disrupt the comms between the pilots and the controllers.
