"Travelling the Skies" A motion filled logo with a colour style that suits the web page. Plane and swoosh with some slight 3D effect and a globe with less pronounced continents.
Modern and strong logo with an open WEB 2.0 styled font. A speedy eagle with swoosh wings that is slightly off centre to the right to give the organization forward momentum.
Very recognizable and easy to adopt for any application.
CH - My recommendation is to move away from air-planes travelling around the globe - unless you consider starting a travel agency for your members? The brand should be more about trust and strength as an association. The members already know their pilots, right? Just my thoughts.
