Origami artist Ana Maria shows us how to fold a reliable paper plane. Start off with a rectangular piece of paper and fold it down the middle. Then take one the of the edges and fold it in a way that it makes a triangle. After that repeat the process again folding the edges even further. Repeat this for the other side as well so that it is nice and even. After making all the folds properly open the page, not the folds made on the edges, then fold it again down the middle but now do it in the opposite direction. After that take the paper from the side and fold it towards the middle to make a triangle again, do this for the other side as well to make the wings for the plane. That is all there is to it, voila, you will have a simple looking plane but it will fly well.
