There must be more than 1,000 decommissioned planes in my own personal history of paper airplane construction. All kinds, too: pointy planes, fat planes, huge ones, tiny ones, planes that flew straight, and others that did loops in mid-air. And here I was, about to give my own son his first glorious taste of printerpaper- made aerodynamics. Keoni looked confused by my suggestion.
