A day to celebrate the development of aviation, Aviation Day falls on and commemorates the birthday of Orville Wright. Federal buildings in America may be required to fly the US flag on this day at presedential whim in order to promote the day, and general interest in aviation. Is there a better day to fly? Take a flight; fly within the country, fly to Spain, fly to Europe. Look up travel deals with companies like Expedia and fly to Sweden, if you’re feeling extreme!
