Crows are famous for their ability to fly between two points by the most direct route.
But aircraft often have to zig-zag because of restrictions on airspace.
Simply by shortening routes, we’ve already cut CO2 emissions by six million tonnes per year. It’s a good start, but there are many more routes we still need to tackle.
This alone won’t solve the problem of global warming. But it is part of a package of practical measures that airlines are taking to limit the 2% of carbon emissions attributed to air transport.

Flying’s a wonderful thing.
