There was a Vulcan that entered a spin on a low speed approach demo into Boscombe Down in the early 1960's. They managed to recover once but it entered a spin in the opposite direction. From memory they deployed the tail brake chute but it broke away. Both pilots (one a Hawker Siddeley test pilot and the other RAF) ejected and survived. The rear crew did not. The aircraft crashed near Andover.
