Looks like this article is progressing nicely in my last edit I caught a few errors but couldn t figure out how to fix the last sentence of the History of paper planes section Perhaps the most accepted version of the creation was in 1909 when Jack Northrop used in the this piece of origami 1930s to test out paper planes so that he could discover ideas for flying real life aeroplanes The sentence falls apart after when Jack Northrop used and it isn t clear what the creation is referring to I presume it should read the creation of a paper plane but the rest of it is muddled 04 35 25 Nov 2004 UTC
