This is a Significant Technology milestone.
The aircraft, a modified Cierva C.7, was piloted by Reginald Truelove. The articulation was installed to reduce the in-plane loads that had lead to an earlier crash of a Cierva C.6C when 2 blades became detached in flight. This would prove to be one the fundamental developments to the successful development of practical rotorcraft.
