As a flight engineer with Kuwait Airways Corp on Comets, ANY crew member could call STOP up to 80kts for a failure-after 80kts, only the "Usual Suspects" (engine fire, failure or o/heat) to V1-(on the Britannia with British Eagle, the F/E applied the reverse as called for by the Captain). Back to the Comet-the Captain would select and apply R/T on both engines and apply brakes whilst the NHP deployed the speed brake. I guess type dictates who does what.
