I believe there was a Cubana IL96 there aswell that diverted from Gatwick and Air Zimbabwe 767 from Harare.
Stansted is a useful diversionary airport, especially for LCY flights as it is just up M11.
Airport managers need to realise Global Warming and the change of weather patterns that the UK gets, bearing in mind it was on Jan this year that we experienced this kind of bad weather before. Its time to study how the scandinavian countries cope each year. Snow equipment is expensive for the amount of time it is in use, but it is a needed tool that all airports must have, the debacle of LGW and in the past LTN has to be overcome, but like everything else, you still have to get humans to drive these pieces of kit and they too have to get into work. Roll on robotic snow ploughs!!
If you cas you mind back to early this year, there were aircraft stuck at STN after diverting from LGW for a day or so, that was due to handling agent running out of de-icing fluid, so that added to the airlines woes, who already had aircraft out of position. Perhaps this time round they stocked up before hand !!
