I grew up in an 10 floor apartment building and I would just fold a few planes and throw them out the window. Now the interesting thing about a street with tall buildings is that on some perfect days the breeze forms these smooth updrafts along the building walls.

My goal was get the paper plane to catch the updrafts and actually climb up from my 3rd floor to the top of the building. It was very rare, I must have tried 10s of different fold types but sometimes conditions would be just perfect and a particular plane would ride up in circles sometimes even clearing the top floor of the building and then glide down and land sometimes hundreds of meters away or even vanish from view.

When I ran out of planes I would grab my bicycle and go out to recover as many of them possible, come back up and repeat...

...sweet times =)
