Anyone know what the current G and other envelope restrictions are for the F35? I remember reading it someplace recently that they still haven't opened up the flight envelope, there is some unclassified info regarding this around on various defense sites. Anyhow, point being that those low level turns were done sans afterburner, and looked pretty relaxed, not being an expert, but sure looked like 5g or less compared to various F16/22/18/15/etc/etc/etc airshow max G turns I've seen on the deck over the years.
That's one thing I'd LOVE to see right about now, an F35 at an airshow doing a really high rate/radius low level turn, to see what it looks like doing so if nothing else.
One thing I'll never argue is that the F35B will give the USMC and the US forces overall a huge advantage and capability boost over the current Harrier. Much easier to fly/land which is a pretty big thing to hear the pilots talk about it, and obviously having a stealth fighter with a much, much better radar and sensor system than the AV8B means the little mini-carrier assault ships will have the ability to do more than just support troops with very, very short range bomb truck runs. Having a squadron of 12 or so B models as well as all the other aircraft types makes new ships like USS America and so on probably more capable than any other nations CVs except maybe France, or once the UK gets its new ones going. I think I've read that the USMC will be able to operate the B from 8 or 9 different assault ships in the fleet right now, with more coming.
