Nato: Cardiff Airport's 'temporary terminal'

The Nato summit in Newport is just a couple of days away. The event will bring scores of heads of government to the Celtic Manor resort as well as thousands of officials, journalists and protesters.
Key venues in Newport and Cardiff are protected by an unprecedented security operation.
At Cardiff Airport, it's "business as usual" but managers, who have been preparing for a year for the summit, have effectively set up a second temporary terminal to deal with all the extra arrivals.
Jason Thomas, chief of staff at the airport, told BBC Radio Wales' Felicity Evans the Ryder Cup and recent Uefa SuperCup events had been good dress rehearsals for handling an even bigger event.
