Dutch roll on B707 has no similarity in Airbus. 707 was notorious for that and whatever little time I had on 707 I experienced it on a commercial flight, yaw damper failure kept causing vicious yaw and turn till I think the weight and altitude reduced to a certain level. I was trained for yaw damper failure in A310 simulator and it was nothing as compared to 707. Airbuses are not prone to this. So KC 135 comparison is futile.
