F1-11 filton
Probably the reason they moved to Farnborough; we still had serviceable arrestor barriers (cables too although I don't think Super Sabres had hooks) even though all the MOD fast jets had gone to Boscombe.
They are hard to see on photos of the Super Sabre as they were somewhat flimsy spring steel affairs that were normally to be found flush with the aircraft underside, just forward of the tail bumper.
Similar to Lightning hooks then; a catch could be released to drop the hook for an overrun end engagement but the hook could not be retracted, it had to be manually lifted back to its stowage position..
