Request for high level ATC stats.

[StillTaxying]

Hi,

I'm writing a presentation and need some help.

I'm after some general stats about the growth of Air Travel in the past 20 or so years, and forecasts (lines on graphs) for what it is expected to do.

I'm looking at it from a UK ATC capacity perspective so I also need some ideas about where the current bottlenecks are and what's planned for the future to manage the increase in traffic.

I've rummaged through the NATS website to no avail.
All ideas/documents gratefuly received.

Thanks.
