A BUNGLING Navy operator accidentally fired a torpedo at a nuclear dockyard that flew across a jetty and smashed into a fence.
Amazingly no-one was hurt when the 9ft missile, which was not armed, was blasted out of HMS Argyll while the ship was moored in Plymouth's Devonport Naval base.

A newly-released file shows the misfire occurred after the operator attempted the test without a mandatory list of safety precautions to hand in March 2014.
The unarmed Sting Ray torpedo flew over a jetty and into a heavy duty metal fence at the high-security dockyard, which services nuclear submarines. Nobody was hurt.
The investigation found that following the information card instructions would have averted the misfire during what was meant to be simulated testing.
It concluded: "The fact that the maintainer was not in possession of the JIC led to a lapse in correct procedure which in turn culminated in the jettison of the TVT [test variant torpedo]."
