He's using the 24-70 f/4 lens wide open (or maybe the 24-70 II at f/4?), a full 2.3 stops slower than your proposed lens, which would have only needed ISO 6400-ish At least, this is what the information on page 1 states. I read the article but didn't see a mentioned aperture (other than "wide open") and "new 24-70" could mean more than one lens
Well-done photo, though, regardless of the noise (which actually could have been removed with some effort, had the inclination arisen).
As for helicopter vibration - I know certain Nikon lenses have a special VR mode called "active", which refers to the platform from which you're shooting is actively moving, aka a vehicle. I'm not sure how well it works, though.
I've also seen a few test shots of Pentaxians shooting from riding lawnmowers with and without IBIS activated - it seemed to work pretty damn well, actually.
