A short instructable on how to make a classic paper airplane, though I doubt many people don't already know how to make one.
Step 1: Folding 1
First, fold a peice of 8 1/2 x 11 or other size sheet of paper in half as shown
Step 2: Folding 2
Then fold the top left and right corners as shown
Step 3: Folding 3
Then, fold the corners again as shown
Step 4: Folding 4
Then, fold the peice of paper in half again, as show. Make sure the folded parts don't get bent.
Step 5: Folding 5
Fold the side down so it lines up with the bottom of the plane as shown. Do th same with the other side
Step 6: TADA!
It's finished! Go fly your new paper plane!
