Spambhoy, you post as though you have direct experience with Aldergrove management. I have met a few of the individuals at various functions, some of them may not come across as the sharpest of characters but you can't deny that as a team, they are currently on a roll. How long it lasts may be up for debate but if its long enough to do Harbour irreparable damage then surely thats their mission accomplished.
I'm not sure how you audit technology and how this audit would lead the an airport being closed, that sounds a bit dramatic! I would suggest any technology is obsolete shortly after it is installed. As far as Harbour reaping benefits, perhaps you should drop their marketing director a quick line, think they need all the suggestions they can get at the minute!
