The Air Canada pavilion traces the history of aviation, expressing the “soul of flight.” Its helical structure consists of 23 blades arranged around a central axis, spanning 80 feet at the base and 30 feet at the top. Inspired by helical forms found in nature and Leonardo da Vinci’s sketches, the architecture also evokes the turbine blades of jet engines. The pavilion is divided into four sections: the dream of flight, the early days of aviation, the social impacts of modern aviation, and recent advances, featuring modern aircraft and electronic equipment.
