The 'aileron upset' system, as it was called on the VC10. Can you imagine, a switch for upsetting your ailerons! I don't know
how they still get away with it in this day and age of laws against bullying and harassment!
The Victor K2 had it's ailerons permanently up-rigged to provide wing bending relief in it's later years.
Permanently upset, they were. Poor ailerons!
