interesting side bar:

In a paper presented at the International Committee on Aircraft Fatigue
(ICAF) 1987 Ottawa Canada, Ian Gray from Bae Filton presented "Fatigue
Crack Propagation Test Programme for the A320 Wing".  Showed that the
flight was more comfortable for the PAX, but the cracks grew faster with
gust alleviation on over crack rates with gust alleviation off.  If you
don't get the gust overloads, you don't get the faigue life!
