I had no clue!
Trevor, there were a vast number of little 'out of the way' places that all had original 'design' uses but over the years became used for many, many different purposes, far from their original concept.
One, down on crew deck, were a couple of 'cells' that were included in the original plans to house 'miscreants', but, with the changes in regulations regarding punishment and how you dealt with crew, they had not been used in years, if ever. Eventually they became storage for the Security Dept, where items only used occasionally and anythnig of value were stored.
On one occasion we had a message from S'ton Office saying that a passenger on a Trannie would be bringing an item that needed secure storage from S'ton to NY.
On embarkation day i was called to the Gangway to meet this Gentleman and escorted him down to the cells to secure his 'package'. We then sealed the double locks, he with one key and me with the other so it needed both to be present to enter the cell. We then covered the locks with numbered security tags and he took photos of the seals with their numbers for proof of security. Twice a day we would meet, check the seals were intact and sign his log book, then he went back to enjoying the crossing with his wife.
Once in NY another man came onboard to witness he breaking of the seals and then to accompany the 'passenger' to a secure location in NY.
The passenger, and his wife, were travelling courtesy of his employers, a firm of Industrial Litigation Lawyers taking a piece of evidence in a multi million dollars law suite in relating to a fractured hydraulic hose. The item had to have a secure transit between locations and it was deemed that QE2 was the most cost effective and secure method.
So this man and his wife, in their early 30s, travelled to NY on QE2 and stayed a couple of days, before flying home Business for about 30 minutes 'work'!!
I even managed to get him an invite the The Captain's Cocktail Party as well as the last night Wardroom Party.
