This was posted a wee while ago, but I was wondering would some of these shots have been "in ground effect"? I've heard FJ mates talking about riding the ground cushion and I've even heard them say that if you're already on/in it, it's actually really difficult to break through it and spank in?
Any thoughts? Or utter horse? Anyone stupid enough to try?
I know that ground effect and ground cushion is familiar to us RW mates and I've experienced it on landing in FW, but never at 300+ kts.
And obviously any anecdotes would be from "a friend of a friend".
Some Gen HEre

Mentions Wing tip vorticies playing an effect, which would suggest as speed increases, induced drag decreases (decreased AOA), therefore wingtip vortex strength decreases, THEREFORE ground effect decreases. Dont know whether you would want to prove this at 420 KIAS within a 1/4 wingspan of the ground!!!!
Someone may know in the tech forum.
