I remember once briefing a bunch of sea cadets that the small silver topped tube next to the broom cupboard was an 'emergency' communications system similar to that seen on WW2 destroyers in case of intercom failure.
The Obs and the crewie played along beautifully.

HIFR was always a pain in the ar$e, not only because it prolonged the flight without the chance to re-stock on 'cheesy, hammy eggies' but also because many of the transfer pumps on the smaller frigates were too weak.
This meant that the hover height required in order to get the fuel flowing put you beautifully into the recirculating downwash from the rotors. Resulting in quite a few troublesome pop surges due to salt water ingestion and salt build up on the IGV's!
Ahhh, the good ol' days
