19. Oh, I "get" what you're asserting

... and, like your fake "767 Vg diagram," asserting it with your own diagram doesn't make it any more valid.

But yes, I did find FAR 25, so you will need to be more careful about simply asserting what is says, too. For example, when you say on your diagram that "Factor of Safety (FoS) is indicated by the orange and yellow regions," you are in effect asserting that Vmo is the speed at which "limit" loads are calculated and Vd is the speed at which "ultimate" loads are achieved, according to the definitions in FAR 25.

So, now, all we need to do is determine if your interpretation is correct. If your interpretation is wrong -- e.g. if Vd is the speed at which limit loads are calculated and an FoS is applied to those loads to get the ultimate loads used in the design calculations, providing a margin of safety beyond Vd -- then your assertion that the 9/11 speeds are "impossible" is bullshit.

Agreed?
