In 1981 I was working in Saudi Arabia and had left to return home for Christmas around the 12th Dec, I guess the temp in Jeddah must have been a minimum of 28 deg C. I had a flight booked from Jeddah to Heathrow and an onward flight to Teesside Airport. Unfortunately snow had fallen all across the UK and Heathrow was snow and fog bound and after circling for ages and a diversion to France we were further diverted to Manchester with the airlines idea of bussing us all down to London. I was halfway home at Manchester and decided to decline the offer and get the train home. The weather in Manchester was literally freezing, there was frost on the inside windows of the train carriage and me in summer clothes for a 2 hour train journey. Sheer agony.
