I can also confirm that those quoted g limits for RAF pax flights are often
very flexible!
I'm also inclined to add that if that original article was really published in a commercial magazine, the publishers ought to be ashamed of themselves. I've seen better written English from five year-olds!
All this reminds me of a couple of rides I scrounged off the Blue Angels a few years back. In typical American "can-do" fashion, they have a miniature TV camera attached to the instrument coaming in their T-Bird's rear cockpit, so they can produce a video for all their happy customers. Unfortunately, when the g load starts winding up past 7g, the recorder head slips of the tape and you lose the picture - so much for technology, doh! Still, this was years ago, maybe they've gone digital now?
