I know the Boeing B-52 wing was supposed to be able to flex a total of
25 feet.  You could tell the fuel state of the bird on the ramp by the
droop in the wings.  One supposes that Boeing would have some continuity
in wing technology.  You might look in a 747 flight manual - no doubt
one is available somewhere on the web.
