I once took a sheet off an A0 flip-chart at my dad's job, and tried to make the biggest paper plane i'd ever seen. It didn't work at all - it was too flimsy, and just collapsed. The paper would have needed to be thicker as well as bigger!

Ha ha, tried a full double-sheet from a newspaper from time to time. You could "loft" it anyway.
