When my daughter and niece were 11 and 9, we had a paper airplane folding afternoon. We went through the handful of designs I remembered from middle school with some level of success. All along, I was teasing them about a super plane I knew how to make.I eventually made it and it flew so much better than all the other ones… but they hated me for it.

It turned out that they wanted paper planes that conformed to their idea of a paper plane, not paper-based engineering marvels.

Apparently, that design is called "two loops".
