Hand Solo :
Thank you for your input, but it seems that if it's not one thing at Heathrow it's another - both runways closed this month (though not for long apparently), LVPs last month, high crosswinds the month before with increased spacing ..... etc. And always the domestic schedule shot for the rest of the day.
Regarding the stands at the end of 23 which had to be cleared, whoever authorised them in the first place ? And the T5 overheight cranes ? Sure it saves BAA costs. But whatever are the CAA airfield licencing people doing about all this ? Nothing it seems, their days being too fully occupied with lining up CBEs for each other.
