I have searched on Instructables, and I'm pretty sure this plane is not in.
This is a very unpredictable plane. I have done many things with it, including:
Gliding across my school's indoor hall (around 50 metres)
Returning like a boomerang.
Returning not like a boomerang.
Going in the opposite direction of throw...
You get what I mean.
Step 1: Materials, and the starting folds
The first few folds are to create a (in Origami terms) "waterbomb base". You can see its construction in the next few steps.
Step 2: Waterbomb base, continued
Step 3: Waterbomb base, finished
Push the two sides in and the waterbomb base is done.
Step 4: Folding the "handle"
Follow the pictures.
A hard step is going to come, so watch out.
Step 5: Don't get stuck on this
Look at the pictures (sorry for the blurred pictures. my camera's macro wasn't that good.) Push one of the "flaps" into the pocket. It is a little tricky.
Repeat with the other side, and (hopefully) you have what is shown in the last picture.
