The earth and it's atmosphere is a dynamic system.
Under the force of gravity, the atmosphere rotates in sync with the land mass,
this means the atmosphere is moving at 1000+MPH right along with the earth.
Since space is essentially a vacuum, there are no obstacles that would disrupt or otherwise interfere with the atmosphere.
Therefore, the airspeed and ground speed of a jet flying any direction depends on atmospheric conditions - weather, wind direction and speed, humidity, air density, altitude, etc.
The ground speed of a jet flying any direction in calm conditions would match the indicated airspeed.
IOW, at an IAS of 470mph, the ground speed would be 470mph.
With a 20mph head wind, the jet would still indicate an airspeed of 470mph, but the speed across the ground would be 450mph.
Conversely, with a tail wind of 20mph, maintaining 470 indicated airspeed, the ground speed would be 490mph.
The rotation of the earth and its atmosphere has no effect on an aircraft's airspeed or ground speed.
It is simply the physics of a dynamic system and is no mystery to anyone with a basic science education.
Or for aviators who deal with the weather every time they takeoff. Been there, done that, many times.

Show us that video - Under the force of gravity, the atmosphere rotates in sync with the land mass.
All you guys got is photoshopped pics jjust like NASA said. Nice try!
