You are just stupid parrot, nothing more. Actual gyro avia horizon does not use gyroscope to show something. It uses gyro as damper for pendulum. Avia horizon task is to stay tangential to Earth surface using gravitaion and sometimes Earth magnetic field in addition as a base, not gyroscope.

Do you have patience to look at steady avia horizon started in wrong position settling to correct one for 10 minutes? Or you just another TikTok generation kid without an ability to understand so long video?

Aviation horizons self-stabilising within few minutes to show what it made for - horizon, not some senseless "orientation in 3D".

It does not "maintain orientation in 3D", because any aviation gyro horizon is made for completely another task.

Laser "gyros" (AKA Sagnac interferometers) are another beasts, but they do not "maintain position in 3D" too. Their output signal is speed of rotation, not position.

Meanwhile laser gyro is one of the cheapest high quality instrument that will show you Earth rotation and curvature you could make in garage by yourself. I think it is also below $100 thing. You will need 1km of raw fiber (~$20 on aliexpress), 4-way 2x2 fiber splitter (~$7 on aliexpress), laser/photodiode combo with fiber connectors from two-eyed SPF or fiber converter (free from garbage bin) or separate laser and diode with fiber connectors (~$20), battery and resistor to power laser(<$1), handful of resistors with OPamp (<$2) and any multimeter (f.e. DT-830 for <$10). All you need is to connect everything and tune your gyro to lowest possible photodiode signal. Any rotation of the fiber coil will cause signal grow. Including rotation of Eath.

About Airey - he assumed that there exists aether presumed to be a substance where electromagnetic waves propagate. Also he assumed that medium dragging aether, depending on it's density. That effect was presumed as a cause of abberation effect on stars. So, he thought that is he will observe star through more dense medium, than, abberation will be larger. But he does not observe that. and that's all. That does not mean that Earth is not moving. That means that there are no aether, or it is dragged equally by any matter.
