One of the biggest and one of the smallest commercial airplanes took to the skies during the past year. In April, the world's largest passenger airliner, the Airbus A380 Navigator, made its maiden flight over the company's Toulouse, France, assembly plant. Soon thereafter the first alcohol-powered aircraft, the EMB 202 Ipanema crop duster, was introduced by Brazil's Indústria Aeronáutica Neiva, a subsidiary of Embraer SA.
