Jetsetwilly et al - somebody must have decided to have been lenient on the Ryanair as Supp 6 to the UK AIP states quite clearly that the last landing aircraft must be on the ground by 23.57 local. In my experience, this has been enforced vey strictly indeed.
Buster - thanks for the link. Doubtless the NIMBYS all think the lack of action is all the fault of the airport rather than the council. Have the local press not done any digging into this - they normally like to take "a pop" at local politicians.
