The video has the plane in it, in case you forget, and plane did not fly in the afternoon.
But the interview was definitely in the afternoon.
Video shows high light, consistent with the time of flight.
We can see a plane flying well above tree tops, while it had been reported that the plane was very low and it even knocked a communication tower and lost some parts.
We don't know what plane that video shows. From the yt clip it is not possible to discern the plane's markings. In short the video within the clip proves nothing.
Some traces of fog are visible but nothing llto the extent characterized in reports.
IF the camera clip shows THAT plane then the clarity of the sky seen there is not conclusive in regards to the fog reports. The plane was not supposed to land on a cloud but on the ground that was reportedly covered by fog.
Again, I encourage you to wait for the official report and, hopefully, for the sound track of the voice recorder. That, I'm sure, will clear any fog. Until then you there is no proof of foul play. None.
