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.
