once made a paper plane that consists of only one wing, but it spins around like a windmill. That was around 1985, the plane takes advantage of any light winds at the time and I flew off a 6th story of the new building at ABAC (today is Assumption University) before other students. It NEVER went down. It keeps going up and up and disappeared from view. I timed the event before it disappeared to well over 10 minutes. Outdoor record unofficially. This is not sensitive to humidity.

This paper plane was made by japanese!Please click this.
