Fan Propelled Paper Airplane (Fake or Real?)

This video has generated half a million views and quite the comment stream on YouTube.

A paper airplane is placed between two fans, and suspends in the air for some time. The comments predominately charge that the action is "fake" (has a wired been suspended?).

The video is an art project by Camille Laurelli. Hard to tell, because her blog is in French, but it looks like the concept of the piece is to generate discussion over the validity of the action.

What do you think? Fake or real? Beyond conjecture or opinion, if anyone has a scientific analysis please write in the comment box below.
