Mr. Bryan Bourke:

It was a mixture. Some people called in unwell. A lot of required regulatory training is under way at the moment. The focus had been very much on making the summer was a better experience than last year and a lot of regulatory training is under way now. If we do not have the people in the tower or somebody has to leave because he or she needs a rest, it may result in what it sometimes called a flow control or closing the space and planes going into a holding pattern. I understand that the planes on Monday night largely arrived on schedule even though they had to wait for a period in holding.
