We used to do that on 90 Sqn Valiants at about that time. Not the most serious of jobs compared with the sprinting by the Victor crews.
When the hooters went in the mess for a Micky Finn at some Godforsaken hour in the morning I could roll over and go back to sleep. After breakfast I would go to the squadron where a the first complete crew in got the job. On one occasion the Squadron Commander was worrying about the fact he only had one serviceable aircraft and he also had to provide a backup. I suggested that he nominate a nearly serviceable aircraft as the ACP and the serviceable one as backup.
That was what was done.
