if i win the lotto sod the merc, i'm getting me a plane!!

problems with pushing the limits on these planes isn't the plane, if i understand right the new ones can do 20G in both directions, however the pilot can't, and i don't think these guys have G suits.
also where as we can build a plane that excells at hovering thats a huge waste when it comes to full size if they optimised it just for hovering.
