In the winter of 1978/9, my wife and I had to wear half the bunny suit each plus our overcoats over the bedclothes each to keep hypothermia at bay due to the appalling state of our RAF Shawbury married quarter, which had only the inner part fitted of what was supposed to be basic double glazing. When the wind blew a three inch gap appeared above the dining room window frame as it blew inwards. The allegedly "warm air" central heating sucked electricity into a black hole inside a cabinet from which no heat ever emerged. That was the year the water in the U bend of the inside loo froze solid.
