In my school days I am making paper flights, it can be fly by throwing them in the air. Really they are flying good. While making them we have to use ordinary paper and small note book size paper will do well for paper flight and it fly very good.

along with trying traditional paper craft designs, i also prepared real looking model of fighter jet with cardboard,
although it was bulky but surprisingly it can fly for few meters if thrown in air
