I took the approach end at Marham mid-90s just after a new RHAG had been installed. It didn't go quite to plan as it just paid out with no retardation until a rather dramatic stop. The cable didn't break but in places it looked more like wire wool and according to the tower there were some rather impressive catherine-wheel like sparks.
It was all a bit of a surprise in the cockpit as one of us had just muttered 'guess we missed it' before the sudden 'ugghhh' moment and the abrupt lift and descent of the nosewheel.
The aircraft was fine and the hook looked fine too but they changed it anyway after advice from the DA.
