Alternate title: Fat stupid idiot plane designed by fucking moron, turns out to presage all modern turbofans.

In high school, I learned to make a paper airplane that was basically this.

Some guy brought one to class and we were all shocked when it glided gently across the room as well as the standard paper dart design.

He taught us all how to make them and you soon saw them all over the school.

Kids loved dropping them from the second-story windows while the teacher wasn't looking.
