Re your << "Not being funny here, but with the airport being closed at 2300, do you think that may explain why most freighters were in before 2300? ">>
Made me smile, although perhaps I should have clarified...
Most ad hoc freight flights come into BHX before 23.00 anyway so the night closures didn't have a massive effect on them anyway
BHX has one of the strictest noise abatement policies anywhere in the UK, due to closeness of housing and night movement are restricted and capped.
Thats probably the main reason why our freight flights mostly operate in the day.
