Control Reversal in WWII

The 707 used outer ailerons only at low speed. Roll control was
provided by inner ailerons. At high speed the outer ailerons
shutdown. I though this was to limit response but it may also have
been to reduce aeroelastic twist.

Fascinating. (Indeed, this has been a fascinating discussion: thank
you all!)

I well remember the first time I flew in a 707, and how startled I was
to realize that the wings which had sagged below my line of sight
while on the ground were now clearly raised by what seemed to be a
matter of several feet.
