Some genius on another forum made a comment yesterday along the lines of "how come East Midlands can cope with the fog whereas Heathrow can't?", the slightly larger volume of movements at LHR obviously not being err, obvious.
Now I'm no expert (far from it, I stack blankets) but even I can see how fog can affect an airport with more movement to a larger degree. Perhaps SKY TV could contact me for a verdict as apparently all the people they speak to are more clueless than me.
Hmmm, perhaps thats a job for me when I leave the RAF, defence/aviation 'expert', can't be much worse than the present hired help.
