US Secretary of State Hillary Clinton has just touched down in Geneva for a series of intergovernmental talks. As she disembarked outside our office window, I was impressed to see her aircraft – a Boeing 757 – fitted out with huge winglets that will help save a lot of fuel. These have been available on the Boeing 737 for quite some time and a lot of airlines are taking advantage of their ability to reduce fuel use (and therefore reduce emissions). Now, as you can see, 757‘s are being equipped and Aviation Partners have launched winglets for the 767 and recently the Airbus 320 aircraft.
