Yup second video definitely faked:
The grass is waving in the wind at the start - but the guy in field never twitches or changes his aiming point whatsoever,
At the point of touchdown (00.52 secs), the grass and tall wild flowers are rock steady,
At 2160p, (4K Def) the spray coming of the undercarriage looks CGI,
Finally, left wing correcting down when wind is from the right is just not on.
But even if it is MSFS, the rendering is better than anything I've seen so far.
