Students fly high with new world record for largest paper plane

Building a paper airplane can be as demanding as building the airframe of a real aircraft. And once a group of students in Pisa set out to make the world’s largest one, the classroom craft turned into a very real engineering problem, tackling stability, weight, stiffness and aerodynamics with an almost surgical attention to every millimeter. The team has now set the Guinness World Record with ICARUS. The paper plane is 7 m (23 ft) long with a wingspan of 20.04 m (65.8 f), weighs in at 28.4
