I saw the firing button was uncovered so I pressed it anyway.
This Wessex Mk5 from 84? Sqn was in the pattern for a Cyprus range with a pair of 14x 2inch rocket projectile (RP) pods. The BOI had been formed to investigate the 2x RPs (solid heads) which had been negligently discharged from the Wessex into/near to someone's garden, while the aircraft was downwind. No one was hurt. It transpired that the Master Armament Safety Switch and the RP pod switches has not been de-selected and that the red cover had not been slid back over the firing button on the top of the cyclic, on climbout from the previous 'in hot'.
