I have heard a rumour that as a contingency plan ahead of the main move, responsible singlies were moved into sub-standard MQ's but the Station Fire Officer put his foot down as they would have to be re-categorised as single accomodation and would therefore need a fire escape.
Oh how the wheel turns full circle. This was happening at Brize (though I think they were excess MQs rather than sub-standard ones) in the early 90s (complete with cooker removal) and still happens at Wycombe as far as I'm aware.
