The place is a joke.Always has been,only the BAA are getting caught out for years of neglect.
The only people that make that place work are the Airport ATC.BAA have no dealings with the helicopters.BAA don't have to deal with 50% of the traffic.BAA don't have to deal with the gridlock when they run out of stands on a daily basis.
I have seen bigger terminals in the Southern Philippines,which is really 3rd world.
Nats has treated the controllers there like s...t for years.They are now just about the lowest paid in Nats,at one of the most complex and difficult to validate Towers in the world.
It's falling to bits,and I couldn't care less
