An older thought, but one I wanted to capture. When visiting Finland – still covered in a blanket of white in mid April – we wondered why Heathrow seems to collapse at the slightest dusting of snow.

It seems it’s partly due to the lack of expertise, equipment and manpower to clear the snow – but given that aeroplanes are overengineered to cope with adverse weather conditions (as you’d hope), there had to be another reason – and after all, Heathrow could learn its lesson and buy a few more snowploughs for next time!

One reason, it seems, is conservatism on behalf of BAA – with every airline in the world flying into LHR, it hardly matters what standards Boeing manufactures their planes to, or the quality of BA’s training. It’s the maintenance staff at Air Qumran and the risk posed by its hungover pilot who’s never even seen a snowstorm, much less landed a plane on an icy runway slick with a fresh dusting of powder.

I don’t blame them on that front. After all – we all learn defensive driving these day so we are prepared with other driver’s competence – why not manage an airport the same way?
