This plane is one of my own designs and is named in homage to the magnificent P-38 Lightning fighter airplane of WWII in having twin fuselages.
Throw underarm quite hard holding the nose between forefinger and thumb or even better throw very hard straight up in the air in a large hall.
If made slightly asymmetrically this plane should gracefully loop down to earth in a wide circle and will stay aloft for a long time. This plane has many of the aspects common to world record beating paper aircraft.
I am really proud of this plane. I created it during a lecture on Particle Physics (yawn) and it flies really well. This plane should be thrown hard and flat, very simple, very fast.
This plane flies well indoors but is useless outdoors as the slightest breeze will make it crash. Hold it very near its shorter edge (the front) underneath the plane. Throw with a pushing motion or overarm so that when you let go it will be level or very slightly tilted downwards. You should find that this plane will glide very slowly for quite a long distance indoors.
This plane is very often biassed to one side or another and will turn this way or that. If you make it absolutely perfect this will not happen but it is practically impossible to make it perfectly.
To throw the paper airplane throw it gently overarm and it will glide in a wide circle down to the ground. I would always advise folding up the wingtips to give the plane more lift.

This paper airplane is best indoors. It is quite stable but any major wind outdoors causes it to crash very quickly.
Try throwing this plane very gently overarm with the nose pointed slightly upwards holding it about a quarter of its length from the nose. In still conditions outdoors or indoors this will let it glide gently for quite a long time and distance.
If you make a flap at the back of one of the wings by snipping the paper twice for about 1cm (1/2″) into the wing and making the two snips and inch (2cm) apart and then folding the paper inbetween the snips up, the paper airplane should gently glide in a circle back to you. Whether the circle is clockwise or anti-clockwise depends on which wing you place the flap (or aerlon).
