BIg surface.. big forces.
The roll was due to yawing a swept wing - not the rudder.
I understand the aerodynamics of roll solely from rudder and I had demonstrated to me in the tanker that one could be in
60 degrees of bank and roll out on a heading when starting only 5 deg from the desired roll out heading.
And as I remember the tanker dash 1 said that a hard rudder could put the airplane beyond 90deg bank in less than 3 seconds. That is a very big force.
