All sorts of Statistics
Since I'm a fan of statistics, this page provides statistics about pretty much everything in the Airports database. They will update with every load of this page, so they're all recent.
The same statistics are used randomly on the main page, which is why you might already have seen some of them before.
These statistics are based on the actual statistics of every airport. Please note that not every airport has statistics - airports without statistics are obviously not listed in any of the modules.
These statistics are based on the runway data for each airport. Please note that runway data may be incomplete, and thus some airports may be missing from the statistics.
These statistics are based on the internal page stats, so basically they're about the server that is serving you the pages.
