If you think things are tough in materials handling, spare a thought for the world's airlines. Last week, the industry's peak body, IATA, noted that the sector last year lost USD10.4 billion. No sooner had the industry shaken off the effects of skyrocketing oil prices, than it had to deal with a huge demand slump due to the global recession. In the face of this business massacre, IATA boss Giovanni Bisignani is philosophical: "Whether this crisis is long or short, the world is changing. Even if we try to look beyond the crisis, we must recognise that it will not be business as usual." Perhaps there's something in that for everyone - even when this crisis is over, we'll all be doing things differently.
