Who remembers the instructor on Hiller 12E's on 705 Squadron who was flying two seaman officers on the air experience Junior Officers Air Course on a mucky day at Predannack - must have been around 1964.
The weather improved and the instructor pointed at the navigation lights switch (labelled as position lights) and said to the centre seat passenger "Switch off the position lights". Unused to a helicopter intercom he heard this as "switch off the ignition" and promptly turned off both magnetos whilst they were at 300 ft downwind.
A successful engine off landing followed.
