I find it interesting because it is the only data that exist that can quantify and contextualize the anecdotal reports of the volume and impact of helicopter use at Davos.
"We went to all this trouble because there is perennial fascination with the flying habits of the 2,800 Davos delegates. Use of private aircraft, though often wildly overstated, highlights the vast wealth and power that descends upon this small skiing town in the Swiss Alps each year. And their transportation choices are frequently criticized for their environmental impact at a conference that seeks solutions to reducing carbon emissions, among other topics."
I was on the island of Sint Maarten for a while. Its a hub in the Caribbean for megayachts and superyachts. You should have a look there around Christmas... Talking about helicopters, wealth and power... And there are many more of those of places and events around the world.
