Had one unusual flight out of Boscombe Down with Bill Bedford in XJ615 investigating the cause of 'rudder buzz' during supersonic pull out. Changing the mass balancing of the rudder system was the cure.
Mmmmmmmn. Rudder buzz on two seaters was still happening in the late '60s by which time every event was fixed dead by the Dunsfold night shift adding a small spoiler strip along the rudder trailing edge.
