Regarding the buffeting shaking comments.
Its bouncing due to the way its being flown, looks like some fast hard manoeuvring speed indicates over 220mph in most of those turns and dives.
The first 30 secs are smooth and the last few secs are too when not flown aggressively.
Again nice bonus and looks great well done all at 1c Team and thanks again for a long awaited video
Edit.
You can see the low level flight buffeting in similar cloud conditions in this vid, look at the pilots shoulders and canopy release handle, now imagine what the buffeting would be like if he pulled the same moves as in the SoW video clip.
